Solid-state imaging device and camera
A solid-state imaging device includes pixels 2 arranged two-dimensionally on a semiconductor substrate 1. In a predetermined area in each pixel is formed a light-sensitive area 3 for receiving incident light 11, and each pixel includes a photoelectric conversion portion 4 for converting the incident light into a signal charge. In at least some of the pixels, the center of the light-sensitive area is offset from the center of the pixel when seen from directly above a principal surface of the semiconductor substrate. Each pixel further includes a light-path change member 12a and 12b for deflecting incident light traveling toward the center of the pixel so as to be directed toward the center of the light-sensitive area. Thus, a solid-state imaging device simultaneously realizing the miniaturization of pixels and a high image quality is provided.
