Title: ELECTROSTATIC TRANSDUCER
Abstract:
Provided is an electrostatic transducer (1) which is small in size and has a large electrostatic capacitance, while having a durable constituent part of a conduction path, said constituent part being connected to an electrode. This electrostatic transducer (1) is provided with a plurality of first electrode sheets (11), a plurality of second electrode sheets (12) and a plurality of dielectric sheets (13). Each one of the plurality of first electrode sheets (11) is provided with a first counter electrode part (11a) and a first terminal electrode part (11b). Each one of the plurality of second electrode sheets (12) is provided with a second counter electrode part (12a) and a second terminal electrode part (12b). Each one of the plurality of dielectric sheets (13) is provided with a dielectric main body (13a), a first extending part (13b) that is interposed between a plurality of first terminal electrode parts (11b), and a second extending part (13c) that is interposed between a plurality of second terminal electrode parts (12b).
