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.

摘要： In a fuel injection device, a control body has a pressure control chamber, an inflow port and an outflow port. The inflow port and the outflow port are opened at an abutting surface exposed to the pressure control chamber. In the pressure control chamber is arranged a floating plate for pressing the abutting surface by a pressing surface with the pressure of the fuel to interrupt communication between the inflow port and the pressure control chamber. The abutting surface of the control body is provided with an outer opposite surface portion opposite to an outer edge of the pressing surface in a displacement axis direction of the floating plate, and the outer opposite surface portion has a special depressed portion that is depressed in the displacement axis direction and that extends along the shape of the outer edge of the pressing surface.

Each outer electrode electrically connected to the inner electrode layers through connecting material is composed of a fixed part, a free part having plural expandable-openings, and a rigid part. The fixed part is electrically contacted with the connection material. A sectional area of the rigid part is rather than that of each of the fixed part and the free part in a width direction of the outer electrode. Each outer electrode has at least one part where the fixed part, the free part and the rigid part are arranged in order in the width direction.
