An optical path delimiter having a lens is disposed so as to be in contact with a transparent lid bonded to a surface of a solid-state image sensor, and is fixed without bonded. Further, the solid-state image sensor to which the transparent lid is bonded, the optical path delimiter disposed so as to be in contact with the transparent lid without bonded, a DSP serving as a signal processor, a circuit part and a wiring board are fixed by being sealed in a synthetic resin. Even when distortion occurs due to warpage, flexure or the like on a board where the solid-state image sensor is disposed, the accuracy of the alignment of the lens with respect to the solid-state image sensor never decreases. In addition, the solid-state image sensor or the signal processor is never damaged by an external shock.
