Abstract:
1. A camera module, comprising: an imaging element having a rectangular light receiving surface; a lens for forming an image on the imaging element; a cylindrical lens barrel that coaxially holds the lens; a spring member that elastically supports the lens barrel such that the lens barrel is movable relative to the imaging element at least in a direction along an optical axis of the lens; and a focus adjustment actuator that moves the lens barrel along the optical axis against a spring force of the spring member, wherein: the lens is formed in a shape obtained by removing a peripheral portion of a circular lens, such that the lens has a reduced size in one direction perpendicular to the optical axis; the lens barrel is formed in a shape conforming to that of the lens as viewed along the optical axis; and a part of the focal adjustment actuator is disposed in a space created on a side of an outer circumferential surface of the lens barrel in correspondence with the removed portion of the lens.
