Abstract:
1. A device comprising: a pickup element having a pixel region having a plurality of light detecting elements; and a cover member that covers the pixel region and is fixed to the pickup element, wherein the cover member has a frame portion fixed to a region surrounding the pixel region, and a flat plate portion disposed over the pixel region with the frame portion and a space therebetween, and an inner wall of the frame portion has a non-vertical surface and an upright surface with respect to a light detecting surface of the image pickup element in an order from the flat plate portion, and satisfies the following expressions: at any point on the upright surface, and at any point on the non-vertical surface, where θA is an inclination angle of incident light with respect to a normal to the light detecting surface, θB is an inclination angle of the non-vertical surface at a point on the non-vertical surface on which the incident light is incident, θC is an inclination angle of the upright surface at a point on the upright surface on which the incident light is incident, H is a height of the frame portion from the light detecting surface, H 1 is a height of the non-vertical surface, H 2 is a height of the upright surface from the light detecting surface, L 1 is a distance from an edge of the pixel region to an upper edge of the upright surface of the inner wall of the frame portion in a direction parallel to the light detecting surface, and L 1 ′ is a distance from the upper edge to a lower edge of the upright surface in the direction parallel to the light detecting surface.
