Abstract
An image pickup unit according to the present invention includes: a lens frame that internally holds an image pickup optical system; and a backside illuminated image pickup device which has a light-receiving section that receives light entering the lens frame via the image pickup optical system and which is held inside the lens frame, wherein a claw portion of the lens frame abuts an opposing surface that opposes a light-entering surface of the image pickup device so as to define a position of the image pickup optical system in an optical axis direction L with respect to the light-receiving section using the opposing surface as a reference.
Claims8
An image pickup unit comprising:
- a frame body that internally holds an image pickup optical system;
- and
- a backside illuminated image pickup device which has a light-receiving section that receives light entering the frame body via the image pickup optical system and which is held inside the frame body, wherein
- the frame body includes an abutting portion that abuts an opposing surface that opposes a light-entering surface on which the light-receiving section of the image pickup device is arranged, and a position of the image pickup optical system with respect to the light-receiving section is defined using the opposing surface as a reference.
An image pickup unit comprising:
- a frame body that internally holds an image pickup optical system;
- a backside illuminated image pickup device which has a light-receiving section that receives light entering the frame body via the image pickup optical system and which is held inside the frame body;
- and
- a substrate electrically connected via an electrode to an opposing surface that opposes a light-entering surface on which the light-receiving section of the image pickup device is arranged, wherein
- an end portion of the frame body on the side holding the image pickup device abuts the substrate, and a position of the image pickup optical system with respect to the light-receiving section is defined using the opposing surface as a reference via the substrate and the electrode.
A method of manufacturing an image pickup unit, comprising the steps of:
- covering an outer circumference of a backside illuminated image pickup device having an image pickup optical system and a light-receiving section that receives light entering via the image pickup optical system with a frame body that internally holds the image pickup optical system and the image pickup device;
- and
- defining a position of the image pickup optical system with respect to the light-receiving section using an opposing surface that opposes a light-entering surface on which the light-receiving section of the image pickup device is arranged as a reference by abutting and adhering an abutting portion of the frame body to the opposing surface.
A method of manufacturing an image pickup unit, comprising the steps of:
- electrically connecting a substrate via an electrode to an opposing surface that opposes a light-entering surface on which a light-receiving section of a backside illuminated image pickup device is arranged, the light-receiving section receiving light entering via an image pickup optical system;
- and
- defining a position of the image pickup optical system with respect to the light-receiving section using an opposing surface as a reference via the substrate and the electrode by covering outer circumferences of the image pickup optical system and the image pickup device with a frame body that internally holds the image pickup optical system and the image pickup device and abutting an end portion of the frame body on the side holding the image pickup device to the substrate.
