Abstract
The piezoelectric layers of a laminated piezoelectric transformer include outermost ceramic layers having first openings defined therein for connection to inner electrodes. The inner electrodes comprise full-face electrodes, each of the inner electrodes having a second opening defined in a corner thereof and filled with an electrically conductive electrode and a third opening defined in another corner thereof and filled with an electrically conductive electrode surrounded by an electrode-free gap. The piezoelectric layers are stacked such that the inner electrodes are alternately electrically interconnected through the-second and third openings which are alternately superposed one on another. The electric generator comprises piezoelectric layers and web-shaped inner electrodes. Each of the web-shaped inner electrodes has a fourth opening defined in at least one end thereof and filled with an electrically conductive electrode.
