Abstract: An electrode unit of the invention includes: an electrode including one end and another end, the other end including a free end; and an electrode supporting portion that supports the one end of the electrode. The electrode is disposed in a second plane that is different from a first plane in which the electrode supporting portion is moved to advance or withdraw when the electrode supporting portion is moved to advance or withdraw in a direction along a longitudinal axis of the electrode supporting portion, and the electrode is supported by the electrode supporting portion via a flexed portion projecting from the first plane to the second plane.

Abstract: In manufacturing method of a cylindrical piezoelectric element, a cylindrical piezoelectric material is formed by molding a piezoelectric material into a cylindrical shape and subjecting the molded piezoelectric material to calcination. A reference electrode is provided on an inner circumferential surface of the cylindrical piezoelectric material. Drive electrodes are provided in a circumferential direction so that the drive electrodes are extending in an axial direction from one end to the other end on an outer circumferential surface. A polarization electrode is provided at a part of the circumferential surface in the vicinity of the one end. A predetermined voltage is applied between the polarization electrode and the reference electrode. The polarization electrode is removed from the cylindrical piezoelectric material.
