To provide a low-profile camera module capable of forming a high-quality image with reduced flare and ghost, at low costs.

Light L obliquely incident from an object side is cut off with the first plate 16a of the top layer, thereby preventing the light from being incident into the openings 16l to 16m of second plates 16b to 16d of layers lower than the top layer. This avoids the incidence of reflected light from the openings 16l to 16m into a photoelectric converter 11a.
