Abstract: A microphone device includes a microphone unit that outputs an electrical signal upon receipt of a sound wave, a microphone case that supports the microphone unit in its inside with cushioning members formed of an elastic material (rubber material), and a microphone cable that supplies the electrical signal from the microphone unit to an output connector attached to the microphone case. A part of the microphone cable is attached in a state of meandering back and forth once or more between one surface and the other surface of the rear cushioning member formed in a flat manner. This configuration allows to suppress transmission of vibration through the microphone cable connected to the microphone unit and prevent generation of vibration noise due to free vibration of the microphone cable.
