摘要： In a boundary microphone, a high-frequency current caused by extraneous electromagnetic waves is prevented from flowing into a microphone case via a microphone cord that is drawn into the microphone case. A portion in which the microphone cord 31 consisting of a two-core shield covered wire is drawn into the microphone case 1 is made a shielding wire exposed part 310 formed by removing a skin 31d, and the shielding wire exposed part 310 is connected electrically to a base part 10 via an electrical connecting means 40 (preferably, a conductive cloth 41, and further preferably, the conductive cloth 41 that is formed into a washer shape having an insertion hole for the shielding wire exposed part 310 and is arranged so as to close a cord insertion hole 12), whereby the high-frequency current caused by extraneous electromagnetic waves is surely prevented from flowing into the microphone case 1.
