Document Type and Number:
WIPO Patent Application WO/2010/001633
Kind Code:
A1
Abstract:
This invention provides an organic piezoelectric material for constituting an ultrasonic vibrator, which has excellent piezoelectric properties and is suitable in high-frequency and broad bands, a process for producing the organic piezoelectric material, an ultrasonic probe using the organic piezoelectric material, and an ultrasonic image diagnosis apparatus for medical application. The organic piezoelectric material is an organic piezoelectric material formed of a high-molecular weight material for ultrasonic vibrator formation. The organic piezoelectric material is characterized in that the content of the residual monomer in the organic piezoelectric material is not more than 200 ppm.
