ORGANIC PIEZOELECTRIC FILM, ULTRASONIC WAVE OSCILLATOR USING THE SAME, METHOD OF MANUFACTURING THE SAME, ULTRASONIC WAVE SEARCH UNIT, AND ULTRASONIC WAVE MEDICAL USE IMAGE DIAGNOSTIC APPARATUS
Document Type and Number:
Japanese Patent JP2009272924
Kind Code:
A
Abstract:

To provide an organic piezoelectric material film with which insulation breakdown will not occur at polarization processing, and to provide a method of forming the same.

In a method of manufacturing an organic piezoelectric material film by extending solution obtained by dissolving an organic piezoelectric material, non-dissolved object in the solution of the organic piezoelectric material is filtered, by using a filtering material that has a hold particle diameter of 10 micrometers or less, and then, the filtrate is extended.
