A camera module 100a includes a lens unit 1a which includes a lens 11 and a lens holder 12 holding the lens 11 therein, and an image sensing unit 2a which includes a solid-state image sensor 24 and a transparent lid section 26 which is arranged so as to face the receiving surface of the solid-state image sensor 24, provided with a space S therebetween. The lens holder 12 blocks unnecessary light to the transparent lid section 26 by engaging the lens holder 12 with a whole periphery part of the transparent lid section 26. Thus, it is possible to provide a solid-state image sensing device, which realizes adequate camera function by blocking unnecessary light to the transparent lid section.
