Abstract
A capacitance type transducer includes one or more cells having a structure in which a vibrating film including one electrode of a pair of electrodes formed spaced apart from each other is supported to be capable of vibrating. The cells are disposed on one surface of a substrate. An acoustic matching layer is provided between a water-resistant sheet and the cells. A water-resistant frame is disposed to surround a side surface of the substrate. The sheet is bonded to an end face of the frame to cover an opening of the frame.
