Abstract:
1. A method for manufacturing an ultrasonic transducer comprising an acoustic matching layer made of a dry gel of an inorganic oxide or an organic polymer, the solid skeletal part of the dry gel having been rendered hydrophobic, a gas shielding case having an inner surface and an outer surface, and a piezoelectric element mounted on said inner surface of said gas shielding case, the method comprising: applying a gel raw material solution to the outer surface of said gas shielding case to thereby deposit said gel raw material solution on said outer surface, said outer surface of said gas shielding case and said gel raw material solution comprising components capable of chemically bonding with one another; solidifying the gel raw material solution to obtain a wet gel; and removing solvent in from the wet gel to obtain a dry gel acoustic matching layer.
