Laminated piezoelectric element |
摘要 |
A laminated piezoelectric element which includes a laminate of piezoelectric ceramic plates and inner electrodes. The piezoelectric ceramic plates are laminated alternately together with the inner electrodes. The laminate is cut so as to have a peripheral surface. A positive outer electrode is connected to one group of inner electrodes at a peripheral surface of the laminate, and a negative outer electrode is connected to another group of inner electrodes at the peripheral surface of the laminate. A coating of fine ceramic particles is applied to, or a ceramic layer is sputtered on, the peripheral surface of the piezoelectric ceramic plates so that the insulation between adjacent inner electrodes is improved. |
