ABSTRACT:
A recording head includes: an actuator having a plurality of operable portions operable to cause the recording head to perform a recording; a drive circuit for driving the 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 operable portions and a second common voltage wire connected to a common voltage portion of the drive circuit. The recording head further includes (A) a conductor for establishing, in an outer surface of the wiring member, an electrical conduction between the first common voltage wire and the second common voltage wire, or (B) conducting means for establishing, in the outer surface of the wiring member, the electrical conduction between the first and second common voltage wires. Also disclosed are methods for manufacturing and inspecting the recording head.
