PROBLEM TO BE SOLVED: To facilitate the mass production and cost reduction of a piezoelectric inverter by improving the versatility of the piezoelectric inverter. SOLUTION: This piezoelectric inverter 2 comprises a piezoelectric transformer 10, a control circuit 12 which controls a frequency of a driving AC voltage for the piezoelectric transformer 10 so as to obtain a set value of the output current of the piezoelectric transformer 10, a drive circuit 20 which drives the piezoelectric transformer 10 according to output signals from the control circuit 12, and one board 4 on which the piezoelectric transformer 10, the control circuit 12, and the drive circuit 20 are mounted and from which a plurality of lead terminals 6 are drawn out. |
