Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a wireless microphone which emits infrared rays around the microphone, includes a simple structure and a small number of components, and improves productivity. SOLUTION: The wireless microphone 1 transmits audio signals by means of infrared rays. A plurality of infrared light emitting elements 17 are mounted on a board 15 in the wireless microphone 1, and at least one of the plurality of infrared light emitting element 17 is disposed on each of both the surfaces of the board 15. A plurality of infrared light emitting elements 17 may be arranged on each of both the surfaces of the board 15 and the infrared light emitting elements 17 may be radially disposed. Infrared rays is emitted around the microphone 1 even without providing an exclusive board for the infrared light emitting element 17 in addition to the board 15. COPYRIGHT: (C)2011,JPO&INPIT
