Abstract
An image pickup module comprises a lens assembly including a lens having a flange part, and a frame component for shading a circumferential surface excluding a neighborhood of a top portion of the flange part in the lens; an image pickup element which the top portion of the flange part touches; and an illumination element arranged around the lens assembly and the image pickup element. The image pickup module is constituted so that exit light from a luminescent surface of the illumination element does not reach directly to an exposed portion that is not shaded by the frame component of the flange part.
