Document Type and Number:
Japanese Patent JP5708444
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a piezoelectric device capable of efficiently and largely deforming a membrane, an ultrasonic probe, and a manufacturing method of a piezoelectric device.SOLUTION: An ultrasonic transmission/reception part 5 as a piezoelectric device in an ultrasonic probe of the present invention includes a circular membrane 6 having a laminated thin plate-like piezoelectric member 62, and electrodes. The electrodes include two or more sets of a pair of first electrodes 63 and 65 and a second electrode 64 provided on the piezoelectric member 62 so as to generate stress opposite to each other accompanying application of voltage respectively to a first area 68 and a second area 69 of the piezoelectric member 62.
