Abstract
A stacked ultrasound vibration device is provided with a plurality of piezoelectric bodies between two mass materials, in which brazing materials with an elastic constant smaller than elastic constants of the two mass materials and the plurality of piezoelectric bodies are used to bond the plurality of piezoelectric bodies as similar material bonding portions by a first metal bonding layer with a first thickness and to bond the plurality of piezoelectric bodies and the mass materials as dissimilar material bonding portions by a second metal bonding layer with a second thickness thicker than the first thickness.
