| 摘要 |
An ultrasound vibration device is provided with a stacked transducer in which a plurality of piezoelectric single crystal element layers are stacked between two metal blocks. Since each of the two metal blocks and the plurality of piezoelectric single crystal element layers is fusion-bonded relative to a stack direction by bonding metal having a melting point corresponding to half a Curie point of the plurality of piezoelectric single crystal element layers or below, it is possible to use non-lead material, reduce a processing cost and realize inexpensiveness. |
