A full bridge circuit composed of four switching elements (Q1 to Q4) is alternated with a high switching frequency and a series-connected resonance circuit composed of an inductor (L2) and a capacitor (C2) is made to resonate for a switching frequency of the full bridge circuit multiplied by an integer (for example, frequency multiplied by three), thereby generating a high voltage pulse for start. After a high-pressure discharge lamp is started, the full bridge circuit is alternated with a low switching frequency so as to operate as a step-down chopper for inverting the output polarity, thereby stably supplying rectangular wave voltage of low frequency to the high-pressure discharge lamp (DL) via a filter circuit composed of an inductor (L1) and a capacitor (C1).

Electrode layers 22A-22C, 24A-24C are formed on both main surfaces of each of piezoelectric layers 20A, 20B. Voltages of different polarities are respectively applied to the electrode layers next to each other on the same main surface and to the electrode layers opposing to each other via the piezoelectric layer. Projection forms 30, 32 are formed in respective edges of the second electrode layers 22B, 24B facing to each other, each of which extends into the opposite area. Through-holes are formed in the piezoelectric layer 20A, 20B, in positions off a division line 38. The electrode layers 22A-22C are connected together by the through-holes 26A, 26B and the projection form 30, to have an equal potential. Those are lead from the diaphragm to the outside, thus reducing the overall thickness. This can reduce the thickness of a piezoelectric sounding body thus obtained and achieves lead reliability improvement, manufacturing process simplification and material diminishing.
