Abstract
A photoelectric conversion element for detecting the spot size of input light. The photoelectric conversion element includes a photoelectric conversion substrate having two main surfaces; a first conductivity-type semiconductor layer and a first electrode layer, which are sequentially laminated on the light receiving surface side, i.e., one main surface, of the photoelectric conversion substrate; and a second conductivity-type semiconductor layer and a second electrode layer, which are sequentially laminated on the rear surface side, i.e., the other main surface, of the photoelectric conversion substrate. The photoelectric conversion element is also provided with an insulating layer that is provided between the photoelectric conversion substrate and the second electrode layer, and the insulating layer has a plurality of through holes that are two-dimensionally provided along the main surface of the photoelectric conversion substrate.
