In a method of forming a thick-film wiring on a substrate, photosensitive-electroconductive paste is filled into a pattern groove formed on the surface of a light-transmitting intaglio plate. The pattern groove corresponds to a desired thick-film wiring pattern. The photosensitive-electroconductive paste filled in the pattern groove are irradiated with light-rays from the front and back sides of the intaglio plate to cause the paste to harden until the overall peripheral surface of the electroconductive paste has a predetermined hardness. The electroconductive paste hardened in the pattern grooves of the intaglio plate is transferred to an intermediate piece. Then, the electroconductive paste is transferred from the intermediate piece to a substrate. Thereafter, the electroconductive paste is fired, whereby a thick-film wiring is formed on the substrate.

The present invention provides a piezoelectric transformer, a piezoelectric inverter, and a liquid crystal display with a high reliability, capable of preventing the occurrence of the soundings caused by the contact between gold thread wires and preventing the breaking of the gold thread wires and the deterioration of the performance of the piezoelectric transformer. The gold thread wire for wiring used in a piezoelectric transformer has a structure wherein band-like metallic foils are wound around a core consisting of numerous fine wires bundled, and the gold thread wire is constituted by impregnating it with wax.

A piezoelectric transformer includes a piezoelectric transforming element supported at its vibrational node region N on a base plate through a resilient adhesive member. Input electrodes of the piezoelectric transforming element are electrically connected to input electrode connecting lands of the base plate through a conductive adhesive which is adapted to be freely deformed according to the vibration of the piezoelectric transforming element. An output electrode of the piezoelectric transforming element is electrically connected to an output electrode connecting land of the base plate through a lead wire or a conductive adhesive.
