ABSTRACT:
A lamination type piezoelectric device includes a piezoelectric member that is longer in one direction, and a plurality of internal electrodes extending substantially perpendicularly to the longitudinal direction and arranged so as to be opposed to each other via piezoelectric layers, respectively. Bending vibration in which the piezoelectric member is bent substantially perpendicularly to the longitudinal direction thereof is excited using a piezoelectric longitudinal effect.
