发明名称 LIQUID EJECTING DEVICE
摘要 A liquid ejecting device (16), including: a flow-path defining member (21) having a pressure chamber (26) formed therein; a piezoelectric actuator (22) constituted by a plurality of layers (22, 32, 37, 40, 41; 72, 75) which includes a piezoelectric layer (37), a common electrode (32; 72), and an individual electrode (34; 74), superposed on the flow-path defining member, and having a through-hole (29) communicating with the pressure chamber; an annular conductor (45) disposed on one of opposite surfaces of the piezoelectric actuator remote from the flow-path defining member such that a part (40, 41; 75) of the layers are sandwiched between the annular conductor and the common electrode, the annular conductor surrounding a periphery of the through-hole; and a liquid supply member (23) having a supply path (64) communicating with the through-hole and bonded to the one of the opposite surfaces via the annular conductor, wherein the annular conductor is connected to a terminal (47) configured to be given a predetermined constant potential and is exposed to a flow path defmed by the through-hole.
