<P>PROBLEM TO BE SOLVED: To provide an organic piezoelectric body enabling, an ultrasonic probe having improved receiving sensitivity, and an ultrasonic vibrator having improved piezoelectric characteristics and heat resistance, to be obtained. <P>SOLUTION: The organic piezoelectric body is a chemical compound having a repeating unit represented by formula (1). In the formula (1), X denotes an oxygen atom or sulfur atom, p denotes integer from 2 to 4, and A denotes an alkylene group or polyoxyalkylene group, and alicyclic ring portion may also be included in the middle of a principal chain of an alkylene group or polyoxyalkylene group. <P>COPYRIGHT: (C)2010,JPO&INPIT |
