Zusammenfassung:	For a light receiving element, signal distortion is suppressed, and an unnecessary space is reduced. The light receiving element includes a plurality of light receiver groups (21g) arranged in an arrangement direction at a predetermined arrangement interval. Light receiver groups (21g) include first light receiver (211) and second light receiver (212). First light receiver (211) has a first main phase portion and a first sub-phase portion having a width of ⅓ of the arrangement interval. First light receiver (211) is separated into first main body portion (211a) and first separation portion (211b) each having a width in the arrangement direction of less than ¼ of the arrangement interval. Second light receiver (212) is separated into second main body portion (212a) and second separation portion (212b) each having a width in the arrangement direction of less than ¼ of the arrangement interval. First main body portion (211a) and second main body portion (212a) are arranged in the arrangement direction, and first separation portion (211b) and second separation portion (212b) are arranged in the arrangement direction.
