摘要：

An ultrasound vibration device 2 is provided with a stacked transducer 41 in which a plurality of piezoelectric single crystal element layers 61 (73) are stacked between two metal blocks 32, 33, 39, 44 (71, 72). Since each of the two metal blocks 32, 33, 39, 44 (71, 72) and the plurality of piezoelectric single crystal element layers 61 (73) is fusion-bonded relative to a stack direction by bonding metal 76 having a melting point corresponding to half a Curie point of the plurality of piezoelectric single crystal element layers 61 (73) or below, it is possible to use non-lead material, reduce a processing cost and realize inexpensiveness.
