Inkjet head and a method of manufacturing thereof

摘要

To provide an inkjet head that maintains a reliable electric connection between a flow channel unit and a common electrode of an actuator unit, a flow channel unit is provided with a cavity formed on an attachment surface of flow channel unit to attach to an actuator unit, and the actuator unit is provided with a contact terminal connected to the common electrode and formed at a position facing the cavity when the flow channel unit and the actuator unit are attached. The common electrode is reliably connected to the flow channel unit through the contact terminal and a conductive material filling the cavity.
