摘要： Provided is a highly durable multi-layer piezoelectric element wherein an external electrode has less possibilities of being peeled off from a side face of a stacked body even when the element is continuously driven for a long period of time in a high electrical field under high pressure. In a multi-layer piezoelectric element (1), a void (2) is formed in a joining interface between a side face of a stacked body (7) wherein piezoelectric layers (3) and internal electrode layers (5) are alternately laminated and an external electrode (9) joined to the side face. Since stress generated in the joining interface between the side face of the stacked body (7) and the external electrode (9) during driving can be reduced by the void (2), there are less possibilities of having the external electrode (9) peeled off from the side face of the stacked body (7) even when the element is continuously driven for a long period of time.
摘要翻译：提供了一种高度耐用的层叠型压电元件，其中即使在高电压下在高电场下长时间连续驱动元件时，外部电极具有从堆叠体的侧面剥离的可能性较小。在层叠型压电元件（1）中，在压电层（3）与内部电极层（5）交替层叠的层叠体（7）的侧面之间的接合界面形成有空隙（2），与侧面接合的外部电极（9）。由于可以通过空隙（2）减小在层叠体（7）的侧面与外部电极（9）之间的接合界面产生的应力，所以外部电极（9）剥离的可能性较小即使元件长时间连续驱动，也从堆叠体（7）的侧面脱离。
