SOLID-STATE IMAGING ELEMENT

Provide is a solid-state imaging element which is capable of efficiently reflecting red light that has transmitted through a photoelectric conversion element toward the photoelectric conversion element, while having excellent red light sensitivity, and wherein a substrate is easily handled during the formation of the element. This solid-state imaging element is configured such that a plurality ofphotoelectric conversion elements 21 are two-dimensionally arranged within a semiconductor layer (20). The semiconductor layer (20) is formed on a supporting substrate (10), in the surface of which aninterlayer insulating layer (22) and a plurality of light-reflecting structures (14) are formed. Each light-reflecting structure (14) comprises a light-transmitting layer (11) and a reflective metal(12) that has the form of a curved surface and covers the surface of the light-transmitting layer (11); and the light-reflecting structures (14) are arranged on the back surface side of the photoelectric conversion elements (21
