Abstract
A laminated-type piezoelectric elementis provided, which comprises a first external electrode layer, which is located at a side area of the laminated-type piezoelectric element, is electrically continuous to internal electrode layers, and comprises plural expansible and contractible opening portionsin a stacking direction of the laminated-type piezoelectric element. As the first external electrode layeris connected to the laminated-type piezoelectric elementwith an electrically conductive adhesive memberand the electrically conductive adhesive memberis narrower than the first external electrode layer, the electrically conductive adhesive memberpenetrates into the opening portionsof the first external electrode layerto form connections in a shape of an anchor. Therefore, the first external electrode layeris firmly connected to the laminated-type piezoelectric element
