<p>Disclosed is an organic piezoelectric material which has particularly excellent heat resistance, while exhibiting excellent transparency, surface gloss, adhesion and piezoelectric characteristics. Also disclosed are an ultrasonic oscillator used in an ultrasonic medical diagnostic imaging device, which is capable of highly sensitively receiving a high frequency wave and suitable for harmonic imaging technique, a method for producing the ultrasonic oscillator, an ultrasonic probe, and an ultrasonic medical diagnostic imaging device. The organic piezoelectric material is characterized in that the piezoelectric material is formed by laminating two or more films at the same time by a coating process.</p> |
