PROBLEM TO BE SOLVED: To obtain a piezoelectric transformer furnished with a high mechanical quality coefficient value Qm, wherein Qm is a piezoelectric ceramic material characteristic value that otherwise degrades almost to a half value in constructing a piezoelectric transformer with the piezoelectric material. SOLUTION: The piezoelectric transformer furnished with a high Qm is constructed by superposing at least two to at most three piezoelectric transformers so as to align respective electrode sections and mutually sticking the transformers by firing, by silver firing, or by solder reflow at high temperature to integrate them into one piece.
