Organic piezoelectric material film, organic piezoelectric material film manufacturing method, ultrasonic vibrator manufacturing method, and ultrasonic medical diagnostic imaging apparatus

摘要

The present invention provides an organic piezoelectric material film having few foreign matters and excellent piezoelectric characteristics. The organic piezoelectric material film of the present invention is a method for producing an organic piezoelectric material film formed by casting and then drying a solution in which an organic piezoelectric material is dissolved in an organic solvent, and the amount of water contained in the organic piezoelectric material film Is 0.1% by mass or less.
