<p>A condenser-type sounding body unit is provided with a casing (10); a plate electrode (1) comprising a conductor; a diaphragm (3) disposed in opposition to the plate electrode (1); a spacer (2) for insulating the plate electrode (1) and the diaphragm (3), the spacer (2) being disposed between the plate electrode (1) and the diaphragm (3); a pair of signal input terminals (6) electrically connected to the plate electrode (1) and the diaphragm (3) respectively; and a sandwiching section (4). The sandwiching section (4) has a first sandwiching section (4A) comprising an insulating material and a second sandwiching section (4B) comprising a conductive material. The sandwiching section (4) sandwiches the plate electrode (1) and the diaphragm (3) from both sides in the direction of opposition thereof. The diaphragm (3), in a state of being affixed to the second sandwiching section (4B), is housed within the casing (10). A sound hole (10A) is formed in the casing (10), in a position in opposition to the diaphragm (3).</p> |
