A multi-optical axis photoelectric sensor, in which external shapes of a light projector and a light receiver are respectively formed by a housing comprising an outer case having an opened front surface and a light transmitting plate for blocking the front surface, and the multi-optical axis photoelectric sensor comprising:
- a storage groove arranged around an outer peripheral part of the outer case;
- and
- a string-shaped elastic member that is interposed between the outer case and the light transmitting plate in a state of being stored in the storage groove, and that seals a gap between the outer case and the light transmitting plate;
- wherein
- at least a part of a side wall of the storage groove is provided with a concave part that is concave in a direction different from a pressing direction from the light transmitting plate to the elastic member, and
- the elastic member comprises a part arranged in the concave part.
