Liquid ejecting device
A liquid ejecting device, including: a flow-path defining member having a pressure chamber formed therein; a piezoelectric actuator constituted by a plurality of layers which includes a piezoelectric layer, a common electrode, and an individual electrode, superposed on the flow-path defining member, and having a through-hole communicating with the pressure chamber; an annular conductor disposed on one of opposite surfaces of the piezoelectric actuator remote from the flow-path defining member such that a part 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 having a supply path 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 configured to be given a predetermined constant potential and is exposed to a flow path defined by the through-hole.
