PROBLEM TO BE SOLVED: To provide an ultrasonic probe which is capable of preventing a piezoelectric element from being destroyed while it is worked or used.
SOLUTION: There are provided a plurality of piezoelectric elements 41 each of which includes a plurality of grooves formed in parallel and which are arrayed along a direction in parallel with the grooves and a compound material 70 with which the plurality of grooves are filled, and which is constituted by mixing a non-conductive granular substance having a thermal expansion coefficient of almost 10
-5 k-1 or less with a non-conductive resin member.COPYRIGHT: (C)2008,JPO&INPIT
