ABSTRACT:
A piezoelectric substrate supporting structure for piezoelectric transformer is provided which, in the supporting and fixing of a piezoelectric substrate on a base plate or in an outer trim case, does not inhibit the vibration of the piezoelectric substrate, exhibits high impact resistance and enables stable supporting, is free from performance deterioration and enables simultaneously and easily performing an electrode takeoff from the piezoelectric substrate. Further, a piezoelectric transformer including the above piezoelectric substrate supporting structure is provided.
The above piezoelectric substrate supporting structure for piezoelectric transformer comprises a piezoelectric substrate 30 as a constituent of piezoelectric transformer 20, which is fitted with electrodes, and conductive supporting members 10A to 10C interposed between portions of the piezoelectric substrate electrodes 34A to 34D and portions of conductive parts 50, 60 disposed on a mounted member 22, 24 for securing the piezoelectric substrate 30, wherein the conductive supporting members are composed of an elastic nonmetal material and a conductive material. Each of the conductive supporting members has its internal part or surface provided with cavities.
