The piezoelectric actuator is provided with a friction and the piezoelectric element. The piezoelectric element generates a first oscillation mode and a second oscillation mode due to the voltage applied at the same time. At the same time it is disposed to the outer surface of the friction portion piezoelectric elements, in contact with the driven member to generate a frictional force between said driven member. At the same time containing a friction portion glass material, and has a glass-containing portion formed to protrude from the outer surface of the piezoelectric element. In the piezoelectric actuator is not limited size of the piezoelectric element, the unevenness is suppressed in the driving state.
