ORGANIC PIEZOELECTRIC MATERIAL FILM, METHOD FOR PRODUCTION OF ORGANIC PIEZOELECTRIC MATERIAL FILM, METHOD FOR PRODUCTION OF ULTRASONIC OSCILLATOR, AND ULTRASONIC MEDICAL IMAGING INSTRUMENT

摘要

Disclosed is an organic piezoelectric material film which has little contaminants and has excellent piezoelectric properties. The organic piezoelectric material film is produced by casting a solution of an organic piezoelectric material in an organic solvent and subsequently drying the resulting product. The organic piezoelectric material film has a moisture content of 0.1 mass % or less.
