摘要： Disclosed herein is a piezoelectric motor. The piezoelectric motor includes a piezoelectric vibrating body, a dummy piezoelectric sheet layer and a contact member. The piezoelectric vibrating body is configured such that piezoelectric sheets on which electrode patterns are printed are stacked on one on another. The dummy piezoelectric sheet layer is provided on the piezoelectric vibrating body. The contact member is provided on the outer surface of the dummy piezoelectric sheet layer. The contact member transmits vibrations generated from the piezoelectric vibrating body to the outside. Therefore, the piezoelectric motor can minimize a problem in which vibration characteristics vary attributable to contact between a contact member and an electrode pattern of a piezoelectric vibrating body.
