Abstract:
1. A recording head, comprising: an actuator including a plurality of operable portions operable to cause the recording head to perform a recording; a drive circuit configured to drive the plurality of operable portions of the actuator; a wiring member on which the drive circuit is mounted, which is joined to the actuator, and which has a plurality of conductor wires including a first common voltage wire connected to a common voltage portion of the actuator that is common to the plurality of operable portions and a second common voltage wire connected to a common voltage portion of the drive circuit, the recording head further comprising one of (A) a conductor configured to establish, in an outer surface of the wiring member, an electrical conduction between the first common voltage wire and the second common voltage wire and (B) conducting means configured to establish, in the outer surface of the wiring member, the electrical conduction between the first common voltage wire and the second common voltage wire wherein each of the first common voltage wire and the second common voltage wore is disposed inside of the wiring member and has an exposed portion exposed from the wiring member, and wherein said one of the conductor and the conducting means is configured to establish the electrical conduction between the first common voltage wire and the second common voltage wire via the exposed portion, wherein the wiring member includes a first conductive layer and a second conductive layer which are provided by the outer surface of the wiring member and which are respectively electrically connected to the exposed portion of each of the first common voltage wire and the second common voltage wire, and wherein said one of the conductor and the conducting means is configured to establish the electrical conduction between the first common voltage wire and the second common voltage wire via the first conductive layer and the second conductive layer.
