To provide a proximity detection device capable of eliminating an undetectable area (6).The proximity detection device of the present invention detects the proximity of an object using a light emitting element (LED) and a light receiving element (PD) that receives reflected light of irradiation light from the light emitting element (LED) reflected by the object. A mirror (100) is provided in proximity to the light emitting element (LED) to reflect part of the irradiation light emitted from the light emitting element (LED) toward an area at which the irradiation light from the light emitting element (LED) does not sufficiently arrive, and a mirror (110) is provided in proximity to the light receiving element (PD) to enable reception of the reflected light from the light emitting element (LED) in a wide range.
