Monolithic piezoelectric transformer and method for manufacturing the same

1. Field of the Invention A monolithic piezoelectric transformer includes a drive portion and a power generation portion. The drive portion includes a plurality of polarized piezoelectric ceramic layers and a plurality of internal electrodes that are alternately layered on each other. The drive portion is provided with external input electrodes connected to the internal electrodes. The power generation portion includes a piezoelectric ceramic member and an output electrode. The internal electrodes are formed of a fired metal containing at least one of silver and palladium and at least one of rhodium and iridium.
