摘要：
A multilayer piezoelectric device comprised of piezoelectric layers and internal electrode layers alternately stacked, wherein the internal electrode layers have a thickness of 1 to 3 &mgr;m and contain 20 to 90 wt % of gold as an essential ingredient, based on 100 wt % of the metal ingredients in the internal electrode layers, and at least one element selected from palladium, platinum, and rhodium.
