Abstract

A capacitance type transducer has a substrate with an opening on a surface thereof, a back plate arranged to oppose the opening of the substrate, and a vibrating electrode film arranged to oppose the back plate across a gap between the vibrating electrode film and the back plate. The capacitance type transducer converts a displacement of the vibrating electrode film into a change in capacitance between the vibrating electrode film and the back plate. The capacitance type transducer has a pressure releasing flow channel which is an air flow channel formed by a gap between a part of the vibrating electrode film and a protruding portion integrally provided on the back plate.
