Abstract

A vibration device comprises a vibrating member having at least n (n≥2) piezoelectric elements arranged on a vibrating plate, each of the piezoelectric elements being formed by using a lead-free piezoelectric material and electrodes, wherein if the temperature that maximizes the piezoelectric constant of the piezoelectric material of each of the n piezoelectric elements is expressed as T(m being a natural number between 1 and n), at least two of Tthrough Tdiffer from each other.
