A lens driving device includes a movable body including a lens support body, and a base configured to support the movable body so as to be able to move in an optical axis direction of a lens. The base includes a base body formed from a resin and having a rectangular plate shape when viewed along the optical axis direction of the lens, and a ring shaped metal member embedded in the base body. The metal member is formed with a projecting portion facing outward at each side of a rectangular shape and exposed from the base body. ## Claims ### Claim 1 A lens driving device comprising: a movable body including a lens support body: and a base configured to support the movable body so as to be able to move in a lens optical axis direction; wherein the base includes a base body formed from a resin and having a rectangular plate shape when viewed along the lens optical axis direction, and an unsplit continuous rectangular ring shaped metal member embedded in the base body; and the unsplit continuous rectangular ring shaped metal member is formed with a projecting portion protruded outward from and facing outward at each of four sides of a rectangular ring shape and exposed from the base body. ### Claim 2 (depends on 1) The lens driving device of claim 1, wherein the base body includes an upstand portion at each of four corners of the base body upstanding in a direction toward the movable body. ### Claim 3 (depends on 2) The lens driving device of claim 2, wherein the upstand portion is formed with a base end portion on a base body side wider in width than at a leading end portion side. ### Claim 4 (depends on 2) The lens driving device of claim 2, wherein the upstand portion is bent at a right angle in a direction orthogonal to the lens optical axis direction. ### Claim 5 (depends on 2) The lens driving device of claim 2, wherein a flexible printed substrate is attachable to the upstand portion. ### Claim 6 (depends on 1) The lens driving device of claim 1, wherein a guide shaft is fixed to the metal member for supporting the movable body so as to be able to move. ### Claim 7 (depends on 2) The lens driving device of claim 2, wherein corners of the unsplit continuous rectangular ring shaped metal member overlap with the upstand portions when viewed along the lens optical axis direction. ### Claim 8 A camera device comprising: a lens driving device; and a lens supported by the lens support body, wherein the lens driving device includes: a movable body including a lens support body: and a base configured to support the movable body so as to be able to move in a lens optical axis direction; wherein the base includes a base body formed from a resin and having a rectangular plate shape when viewed along the lens optical axis direction, and an unsplit continuous rectangular ring shaped metal member embedded in the base body; and the unsplit continuous rectangular ring shaped metal member is formed with a projecting portion protruded outward from and facing outward at each of four sides of a rectangular ring shape and exposed from the base. ### Claim 9 An electronic apparatus comprising the camera device including: a lens driving device; and a lens supported by the lens support body, wherein the lens driving device includes: a movable body including a lens support body: and a base configured to support the movable body so as to be able to move in a lens optical axis direction; wherein the base includes a base body formed from a resin and having a rectangular plate shape when viewed along the lens optical axis direction, and an unsplit continuous rectangular ring shaped metal member embedded in the base body; and the unsplit continuous rectangular ring shaped metal member is formed with a projecting portion protruded outward from and facing outward at each of four sides of a rectangular ring shape and exposed from the base.
