The proximity sensor includes a detection coil, a metal head housing, and a power supply cable. The detection coil generates a detection current. The metal head housing houses the detection coil. The power supply cable has an electrical connection with the detection coil and is connected to the metal head housing. At least a part of an internal space of the metal head housing is filled with a filler so as to bury the detection coil. As the filler, an adhesive and an additive having a relative permittivity lower than that of the adhesive are mixed.
