ABSTRACT:
A piezoelectric transformer (101) comprises a layered structure (15) formed by alternately stacking a plurality of internal electrodes (13) and a plurality of piezo-electric ceramics layers (103) in thickness direction, first electrodes (21, 23) formed on side surfaces of said layered structure (15) and connected to said internal electrodes (13), at least one pair of second electrodes (27, 29, 31, 33, 35, 37) formed on the side surfaces in areas different from those of the first electrodes (21, 23) and having a same potential, and a circuit board for driving the piezoelectric transformer. The piezoelectric transformer (101) is mounted on the circuit board. Each of the at least one pair of the second electrodes (27, 29, 31, 33, 35, 37) opposite to each other is electrically connected to the circuit board.
