PROBLEM TO BE SOLVED: To provide a wireless sensor which includes a mounting base to be fixed to a wall surface or a ceiling surface and a sensing head to be mounted on the mounting base so as to be freely attachable/detachable, and which has an antenna projected from a cover section, wherein the wireless sensor is prevented from falling from the mounting base even when the sensing head receives an impact. SOLUTION: A locking means 2 for preventing the reverse rotation of the sensing head 11 is installed on an inner peripheral face near the antenna 17 of the cover section 12 and at a position corresponding to the outer peripheral face of a guide section 23.
