摘要:
A laminated-type piezoelectric element 1 is provided, which comprises a first external electrode layer 33, which is located at a side area of the laminated-type piezoelectric element 1, is electrically continuous to internal electrode layers 21, and comprises plural expansible and contractible opening portions 33a in a stacking direction of the laminated-type piezoelectric element 1. As the first external electrode layer 33 is connected to the laminated-type piezoelectric element 1 with an electrically conductive adhesive member 32 and the electrically conductive adhesive member 32 is narrower than the first external electrode layer 33, the electrically conductive adhesive member 32 penetrates into the opening portions 33a of the first external electrode layer 33 to form connections in a shape of an anchor. Therefore, the first external electrode layer 33 is firmly connected to the laminated-type piezoelectric element 1.
