Abstract:
A piezoelectric substrate supporting structure for a piezoelectric transformer, comprising:a piezoelectric substrate having electrodes; anda conductive supporting member for supporting the piezoelectric substrate to a mounting member;one end of the conductive supporting member being contacted to the electrode formed on the surface of the piezoelectric substrate,the other end of the conductive supporting member being contacted to a conductive member formed on the surface of the mounting member,said conducting supporting member comprising an elastic nonmetal material and a conductive material,a section of the conductive supporting member consisting essentially of at least three layers composed of a first resin layer, a conductive layer and a second resin layer arranged in this order from an inside toward an outside of the conducting supporting member,at least one of the first resin layer and the second resin layer comprising an elastic material, andthe conductive layer comprising a conductive material,said first resin layer comprising a through-hole passing through in the vertical direction from the piezoelectric substrate to the mounting layer.
