PROBLEM TO BE SOLVED: To suppress the entire power consumption with respect to vibration suppression by reducing voltage amount to be applied to a single piezoelectric element compared to a conventional element while maintaining the displacement amount of a desired SIMM board, in a piezoelectric device having a piezoelectric element provided with a piece of rectangular/planar piezoelectric ceramic substrate. SOLUTION: A plurality of long piezoelectric elements 10 are joined and arranged in parallel on the SIMM 11 board in a state where gaps are provided in a direction of crossing the piezoelectric elements 10 at right angles.
