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)tanθB≰L1 andθB>θC at any point on the non-vertical surface, whereθA 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.
