摘要：
A method of producing a cylindrical piezoelectric element includes: (a) injecting the molding fluid containing calcined powder of piezoelectric material in a mold having cylindrical cavity and wire-shaped core inserted therein; (b) heating to dry the molding fluid injected in the mold so as to obtain cylindrical member; (d) removing cylindrical member from the mold; and (e) sintering the cylindrical member to obtain a piezoelectric element.
