ABSTRACT:
A piezoelectric transformer includes a piezoelectric plate in which a pair of cuts are formed in the piezoelectric plate at a position corresponding to a nodal point of the piezoelectric plate. The pair of cuts form a cut-out projection. Connection electrodes electrically connected to input electrodes are respectively formed on input-side cut-out projections. In this piezoelectric transformer, the desired support and electrical connection are made through the cut-out projections.
