Abstract:
A thermal poling method in which a poling treatment can be performed easily by a dry process. The poling treatment is performed on a PZT film by performing a heat treatment on the PZT film under a pressurized oxygen atmosphere at a temperature of 400° C. or more and 900° C. or less. The PZT film before the heat treatment has a single-domain crystal structure, and the PZT film after the heat treatment has a multi-domain crystal structure.

Claim (Index 2):
The inspection method of piezoelectric property according to  claim 1 , wherein\n said first ferroelectric film has a single-domain crystal structure, and said second ferroelectric film has a multi-domain crystal structure.
