Abstract:
An acoustic matching member is fitted to a main body in a pair of ultrasonic transmitter/receivers. The acoustic matching member includes a matching member equipped with a porous body adhered tightly to an acoustic-wave emission surface of the main body. A dense layer is stacked on a surface of the porous body and includes a thermosetting resin and first flowability-diminishing particles. A sidewall member is adhered tightly to the acoustic-wave emission surface and an end face of the porous body.
