PROBLEM TO BE SOLVED: To provide a wireless microphone capable of performing stable operation even when the microphone is brought into contact with a human body or a peripheral metallic body. SOLUTION: A wireless microphone 1 is provided with a microphone unit 2 and a lead wire 11 for connecting the unit 2 to the input part of a transmission circuit 6 through a high frequency choke 10. The output part of the circuit 6 is connected to a connection point P between the wire 11 and the choke 10. Thereby the unit 2 and the wire 11 become hot side antenna elements and a grounded conductor 13 becomes a cold side antenna element.
