Abstract
A cover member fixed to a pickup element has a non-vertical surface and an upright surface and satisfies H2 tan(θA−2θC)≦L1+L1′ at any point on the upright surface, and H tan(θA−2θB)+(H1)tan θB≦L1 and θB>θC at any point on the non-vertical surface, where θA is the inclination of incident light, θB is the inclination at a point on the non-vertical surface, θC is the inclination at a point on the upright surface, H1 is the height of the non-vertical surface, H2 is the height of the upright surface, H is the height of the frame portion, L1 is the distance from the edge of a pixel region to the upper edge of the upright surface, and L1′ is the distance from the upper edge to the lower edge of the upright surface in the planar direction.
