METHOD AND DEVICE FOR MANUFACTURING LAMINATED PIEZOELECTRIC TRANSFORMER

PROBLEM TO BE SOLVED: To provide a method and device, by which a high reliability laminated piezoelectric transformer can be manufactured at a reduced manufacturing cost through a reduced number of manufacturing steps. SOLUTION: The method comprises a first step of forming at least an input electrode in a prescribed area of a ceramic green sheet, a second step of forming a laminated piezoelectric element, by cutting the green sheet into pieces of a desired dimension and integrally baking the pieces, after the pieces are superimposed upon another, and a third step of forming edge electrodes for outside connection, by partially applying paste of an electrode material to one edge of the crystal element by means for a mediating jig. The method also comprises a fourth step of polarizing a prescribed area of the crystal element.
