Light-receiving element, x-ray imaging element, and electronic apparatus

An X-ray imaging element comprising a plurality of light-receiving elements generating signal charge based on an X-ray,

• the light-receiving elements each including
• a semiconductor substrate including a photoelectric conversion region,
• a first first electrically-conductive region provided at an interface of a first surface of the semiconductor substrate and coupled to a first electrode,
• a second first electrically-conductive region provided at the interface of the first surface and around the first first electrically-conductive region and coupled to a second electrode,
• a third first electrically-conductive region provided at the interface of the first surface and around the second first electrically-conductive region and being in an electrically floating state, and
• an electrically-conductive film provided above the first surface at least between the first first electrically-conductive region and the second first electrically-conductive region.
