ABSTRACT:
In a piezoelectric transformer unit which transforms an input voltage into an output voltage and which includes a piezoelectric transformer element driven by high electric power, a package is provided to accommodate the piezoelectric transformer element therein. Electrodes are attached to nodes of the piezoelectric transformer element and supported by each pair of input and output conductive leads which are operable as leaf springs and which are extended through the package. Contact portions of the conductive leads may provide point contacts, area contacts, and/or line contacts.
