Abstract: The present invention is piezoelectric ceramic step-up transformer and its making process. The mechanical serial structure in the input end and the output end are utilized to produce resonance, and raised voltage is output with high electric power converting efficiency. The piezoelectric transformer is produced via co-baking process and has the features of compact structure, small size, stable performance and the small cuboid structure. During the making process, bending vibrating mode is introduced. The transformer is suitable for use in small electronic instrument.
