PIEZOELECTRIC BODY MANUFACTURING METHOD, PIEZOELECTRIC BODY, ULTRASONIC PROBE, ULTRASONIC DIAGNOSING DEVICE, AND NONDESTRUCTIVE INSPECTION DEVICE

WIPO Patent Application WO/2003/045111

A1

A piezoelectric body manufacturing method for realizing a highly reliable ultrasonic diagnosis by using one or more piezoelectric bodies of a same shape accurately manufactured so as to provide a thickness distribution, the piezoelectric bodies, an ultrasonic probe, an ultrasonic diagnosing device, and a nondestructive inspection device, the method comprising a piezoelectric precursor forming step for forming the mixture of piezoelectric material made of piezoelectric ceramics powder with binder dissolved in solvent in a sheet with a thickness of several ten microns to several hundred microns by a doctor blade method, piezoelectric precursor laminating steps (a) and (b) for laminating a sheet−like piezoelectric precursor (6) thus obtained, pressurizing steps (c) and (d) for molding piezoelectric precursor laminated bodies (7) thus obtained, and a baking step (e) for baking a pressurized piezoelectric precursor laminated body (7a) to a specified shape.
