Abstract: A photodetector that makes it possible to attempt to improve optical characteristics in terms of oblique incidence of light at angle-of-view ends is provided. A photodetector includes multiple pixels arranged in a matrix on a semiconductor substrate. Each of the multiple pixels includes a photoelectric converting section that photo-electrically converts incident light, and a deflecting section that is arranged on a light-incidence-surface side of the photoelectric converting section, and has multiple pillars with different thicknesses, pitches, or shapes in the pixel. The pillars guide an incident principal ray that is incident at a different angle for each image height to the photoelectric converting section at a prism angle at which light is bent relative to the principal ray differently for each pixel.
