The lens holding member holds at least one lens. The base member has a contact surface that is perpendicular to an optical axis of the lens, and contacts an end face of the lens holding member in a state wherein the lens holding member is held; and an opening portion through which passes the optical axis of the lens, provided in the contact surface. The substrate has an imaging element on which light that has passed through the lens and through the opening portion of the base member is incident. ## Claims ### Claim 1 An imaging device comprising: a lens holding member holding at least one lens, and comprising, on the image side of the lens, an end face that is perpendicular to the optical axis of the lens; a base member holding the lens holding member, comprising a contact surface that contacts the end face of the lens holding member, in a state wherein the lens holding member is held, and that is perpendicular to the optical axis of the lens, and comprising an opening portion that is provided in the contact surface and through which the optical axis of the lens passes; and a substrate, secured to the base member, that has an imaging element on which light that passes through the lens is incident after passing through the opening portion of the base member. ### Claim 2 (depends on 1) The imaging device as set forth in claim 1, wherein: the base member has a side face that is continuous with the contact surface and that has a side face that surrounds the outer peripheral surface of the lens holding member in a state wherein the lens holding member is held; and securing material is provided between the outer peripheral surface of the lens holding member and the side face of the base member. ### Claim 3 (depends on 1) The imaging device as set forth in claim 1, wherein: the contact surface of the base member has a circular ring-shaped protruding portion that encompasses the optical axis of the lens, at a peripheral edge portion of the opening portion; the lens holding member is of a round cylindrical shape, and has a circular ring-shaped recessed portion between the inner peripheral surface and the end face; the inner diameter of the circular ring-shaped recessed portion of the lens holding member is larger than the outer diameter of the circular ring-shaped protruding portion of the base member; and the depth of the circular ring-shaped recessed portion of the lens holding member is deeper than the height of the circular ring-shaped protruding portion of the base member. ### Claim 4 (depends on 1) The imaging device as set forth in claim 1, wherein: at least one of the base member and the substrate has a positioning portion that matches the position of the substrate to a position for securing the base member; and the securing member securing the substrate to the base member secures the substrate to the base member at a position wherein the distance of the substrate from the center of the imaging element is less than the distance between the positioning portion and the center of the imaging element of the substrate. ### Claim 5 (depends on 1) The imaging device as set forth in claim 1, wherein: the lens holding member is equipped with a lens barrel holding the lens, and a barrel holder, holding the lens barrel, that has the end face. ### Claim 5 (depends on 5) The imaging device as set forth in claim 5, wherein: a first biasing member biasing the lens barrel in respect to the barrel holder, is provided between the lens barrel and the barrel holder. ### Claim 6 (depends on 5) The imaging device as set forth in claim 5, wherein: the lens barrel is of a round cylindrical shape and comprises a first screw-fastening portion that is provided on the outer peripheral surface thereof, and a first reduced diameter portion that is provided further toward the image side of the lens than the first screw-fastening portion and that has an outer diameter that is less than the outer diameter of the first screw-fasting portion; and the barrel holder is of a round cylindrical shape and has a second screw-fastening portion, provided on an inner peripheral surface, for screwing together with the first screw-fastening portion of the lens barrel, and a second reduced diameter portion that is provided further toward the image side of the lens than the second screw-fastening portion and that has an inner diameter that is less than the inner diameter of the second screw-fastening portion, wherein: the first reduced diameter portion of the lens barrel is inserted into the second reduced diameter portion of the barrel holder. ### Claim 8 (depends on 1) The imaging device as set forth in claim 1, comprising: a second biasing member biasing the lens holding member in respect to the base member. ### Claim 9 (depends on 8) The imaging device as set forth in claim 8, wherein: the second biasing member is secured to the base member. ### Claim 10 (depends on 8) The imaging device as set forth in claim 8, wherein: the second biasing member contacts a portion of the lens holding member from the object side of the lens to bias the lens holding member. ### Claim 11 (depends on 5) The imaging device as set forth in claim 5, wherein: the lens barrel of the lens holding member has a flange portion that extends out in a direction that is perpendicular to the optical axis of the lens; and a third biasing member is provided for contacting a portion of the flange portion of the lens barrel from the object side of the lens, to bias the lens barrel and the barrel holder in respect to the base member. ### Claim 12 (depends on 11) The imaging device as set forth in claim 11, wherein: the third biasing member is secured to the base member. ### Claim 13 (depends on 1) The optical device comprising: an imaging device as set forth in claim 1. ### Claim 14 (depends on 1) The electronic device comprising: an imaging device as set forth in claim 1. ### Claim 15 A method for manufacturing an imaging device that comprises: a lens holding member holding at least one lens, and comprising, on the image side of the lens, an end face that is perpendicular to the optical axis of the lens; a base member holding the lens holding member, having a contact surface that contacts the end face of the lens holding member, in a state wherein the lens holding member is held, and that is perpendicular to the optical axis of the lens, and comprising an opening portion that is provided in the contact surface and through which the optical axis of the lens passes; and an imaging element on which light that passes through the lens is incident after passing through the opening portion of the base member, wherein: said method of manufacturing the imaging device includes: adjusting a position of the optical axis of the lens and of the imaging element through moving the lens holding member in a direction that is perpendicular to the optical axis of the lens in a state wherein the end face of the lens holding member is in contact with the contact surface of the base member.
