Abstract
An aspect of a piezoelectric actuator according to the present invention comprises: a plate-like piezoelectric element (); a sheet (); and a movable body (). The piezoelectric element is provided to the sheet () in such a manner that the upper surface of the plate-like piezoelectric element is parallel to the upper surface of the sheet. The sheet includes a movable body driving section () formed on one of the upper and the lower surfaces of the sheet. A movable body includes a contact section () contacting with the sheet at the movable body driving section. The actuator moves the movable body driving section in a direction parallel to the upper surface of the sheet by using expansion and contraction of the piezoelectric element in a direction parallel to the upper surface of the piezoelectric element to move the movable body.
