ABSTRACT:
There is provided with a piezoelectric transformer which does not require a marking operation, is easy to manufacture, and is capable of reducing costs. After the piezoelectric transformer is manufactured, a shape of secondary side electrodes on the outer end is made so that a polarization direction can be recognized at the time of printing the secondary side electrodes without marking by a separate step to recognize the polarity on the primary side.
