Abstract
A piezoelectric transformer comprises one or more input parts having first internal electrodes and input terminals and an output part having second internal electrodes and output terminals. Each of the second internal electrodes has an area larger than that of each of the first internal electrodes. By such configuration, output power is increased while heat generation is suppressed and size thereof is not increased.
