Piezoelectric actuator and liquid-droplet ejection head |
摘要 |
A piezoelectric actuator disposed on a surface of a flow-path forming member may comprise a first piezoelectric layer disposed farthest from the surface of the flow-path forming member. The piezoelectric actuator may comprise a surface electrode disposed on one surface of the first piezoelectric layer opposite the surface of the flow-path forming member. The piezoelectric actuator may comprise a land bonded to a terminal of a power supply member. The piezoelectric actuator may comprise a continuous detection electrode including an outer peripheral portion extending along the outline of an area that opposes the land to surround the area and being disposed on one of the other surface of the first piezoelectric layer and a surface of a second piezoelectric layer.
