Abstract: Substantially uniform rigidity is ensured in all radial directions while achieving a size reduction. An ultrasonic surgical apparatus is provided, including a polygonal columnar elastic body that is formed of an elastic body and that has a substantially regular polygonal cross-section; plate-like piezoelectric elements that are secured to mutually opposing side surfaces of the polygonal columnar elastic body and that are polarized in a plate-thickness direction; a rod-like contactor that is secured to an end of the polygonal columnar elastic body and that has a smaller diameter than the polygonal-columnar elastic body; and a drive-pulse generating circuit that causes the rod-like contactor to ultrasonically vibrate by generating a vertical vibration which expands/contracts the polygonal columnar elastic body in the longitudinal direction by applying an AC voltage to the piezoelectric elements in the plate-thickness direction.
