A microphone including a light emitting part can be miniaturized. The microphone includes: a microphone unit; an impedance converter that converts output impedance of the microphone unit; a light source that notifies an operation state of the microphone unit; a conversion substrate on which the impedance converter is mounted; a light source substrate on which the light source is mounted; and a connection substrate to which a signal line for transmitting a signal from the impedance converter and a power line for transmitting power to the light source are connected. The conversion substrate, the light source substrate, and the connection substrate are three-dimensionally connected to one another to constitute one substrate unit.

The present invention provides a light guide body for a microphone that radiates light from a small number of light sources toward a surrounding of a microphone with a uniform quantity of light. The light guide body for the microphone that guides light from one or more light sources which emit light in accordance with operating a state of a microphone unit of the microphone. The light guide body has a plate shape and comprises one or more incident surfaces on which light from the light source is incident, and one or more grooves, each of which includes a reflecting surface that reflects light incident on the incident surface.
