PROBLEM TO BE SOLVED: To provide an output connector of a microphone capable of surely blocking intrusion of an electromagnetic wave with even a high frequency generated from a mobile phone or the like into the microphone. SOLUTION: The output connector 10A of a 3-pin type formed by penetratingly providing a first pin E for earthing, a second pin SH and a third pin SC for receiving a signal to a connector base 11 made of an electric insulator includes: a printed wiring board 100 located on the connector base 11; and a shield cover 200 for covering the printed wiring board 100, the printed wiring board 100 is a double-sided board the lower side of which has a shield layer made of a copper foil solid pattern and on the upper side of which a capacitive element for blocking intrusion of a high frequency signal and a Zener diode element for preventing circuit destruction due to static electricity are mounted in parallel, and nearly the entire upper face of the board is covered by the shield cover 200.
