Piezoelectric displacement element

Abstract

Abstract PURPOSE:To facilitate the electric connection to an electrode layer in a ceramic layer by forming a through hole in a ceramic layer an externally leading the electrode layer disposed in a piezoelectric ceramic layer through the hole via a lead conductor. CONSTITUTION:An electrode layer 33 is formed in piezoelectric ceramic layers 31, 33, and formed parallel to the layers 31, 32. A through-hole 34 is formed at the end of the layer 31, a lead conductor 35 is connected to the hole 34, electrically connected to the layer 33, and the layer 33 is externally led. As a result, the electric connection to the electrode layer disposed therein can be facilitated, and since the ceramic layer is integrally sintered, mechanical strength can be increased.
