A microphone element having a diaphragm and a fixed electrode disposed opposite to each other on a silicon board having a central opening portion is mounted and fixed onto a base board having a sound hole. A perimeter-shaped side board and a cover board are mounted and fixed onto the board, thereby forming a back cavity on an upper side of the microphone element. The diaphragm and the fixed electrode are conducted to conductive layers of the cover board through conductive layers of the base board, and a conductive layer and a coiled spring in the side board respectively, and mounting on a surface of a printed board of an external apparatus can be carried out in a conductive layer on an upper surface thereof. |
