Document Type and Number:
WIPO Patent Application WO/2015/111621
Kind Code:
A1
Abstract:
This stacked ultrasonic vibration device (2) is provided with: a stacked piezoelectric body unit (75) in which a plurality of piezoelectric bodies (61) and a plurality of electrode layers (62, 63) are stacked and integrated; a first bonding material (73) which bonds together the plurality of piezoelectric bodies (61), and which melts at a first bonding temperature that is lower than half the Curie temperature of the plurality of piezoelectric bodies (61); and a second bonding material (76) which bonds together the stacked piezoelectric body unit (75) and two mass members (42, 43), and which melts at a second bonding temperature that is lower than the first bonding temperature, and higher than the maximum temperature during driving.
