Patent ID: 7988371

Claim:
A camera module comprising: a substrate module that comprises an imaging device having a pixel where photo-electric conversion is conducted, and a substrate to which the imaging device is fixed; a lens that is formed of a resin material having a heat-resistance temperature higher than a heating temperature in a mounting process of an electric component, and transfers an image to the imaging device; and a lens holder that holds the lens directly or indirectly and that is formed of a resin material having a heat-resistance temperature higher than the heating temperature in the mounting process of the electric component, the lens holder being coupled to the substrate module; wherein a coefficient of thermal expansion of a material of the lens is α 1 and a coefficient of thermal expansion of a material of a portion of the lens holder for holding the lens is α 2 , and a relationship of 1<α 1 /α 2 ≦20 is satisfied.
