Abstract
A method for manufacturing an acoustic matching member, the acoustic matching member being incorporated into an ultrasonic transducer for transmitting and receiving ultrasonic waves, and including: at least two layers including a first layer and a second layer that have different acoustic impedance values from each other. The method for manufacturing including the steps of: filling voids of a porous member with a fluid filling material, and solidifying both the fluid filling material inside the voids and the surplus fluid filling material at the same time. The acoustic matching member does not have independent intermediate layers between the layers, so that delamination hardly occurs and the difficulty in the designing associated with the presence of intermediate layers can be avoided.
