PROBLEM TO BE SOLVED: To efficiently control mechanical vibration generated when a flexible pipe is bent in a microphone in which a microphone unit is supported with the flexible pipe. SOLUTION: The insulating sheath of a microphone cable to be inserted into the flexible pipe is made of an elastic body having rubber elasticity, and a rib 55 contacting the inner surface of the flexible pipe in a state of being compressed with deformation is formed on its outer peripheral.
