Abstract
A plurality of photoelectric converters is formed on a semiconductor substrate and performs photoelectric conversion according to incident light. A light path portion includes a transparent film through which the incident light is transmitted, a light-blocking wall for each of the plurality of photoelectric converters, the light-blocking wall partitioning the transparent film in a direction perpendicular to the semiconductor substrate, and blocking light, and a light-blocking film at an end of the light-blocking wall, the end being opposite to an end of the light-blocking wall that is closer to the semiconductor substrate, the light-blocking film having a film shape parallel to the semiconductor substrate, and including, for each of the plurality of photoelectric converters, an opening through which the incident light is transmitted. An on-chip lens is arranged for each of the plurality of photoelectric converters, and collects the incident light into the photoelectric converter through the light path portion.
