Abstract
A microphone () is fitted with a mounting portion () of a front case () in a state being set to a microphone folder (). A metallic mesh-wise sheet () is attached to a front face of the microphone. When an EL sheet () on a rear face of the front case emits light by supplying power to it, electrical noise is radiated from the EL sheet. The mesh-wise sheet of the front face of the microphone blocks the electrical noise from the EL sheet, which may enter through a sound hole () to the inside of the microphone.
