摘要： An ink-jet head includes two side cover plates (shield plates) (53) extending on the surface of the passage unit (4) in a longitudinal direction of the passage unit (4). Two shield plates (53) confront each other. The surface of the passage unit (4) is provided with two grooves (4a) extending up to the middle of the passage unit in a thickness direction of the passage unit (4). The shield plate (53) is provided at its circumference with a contact line linearly extending and coming into contact with a plane formed on the surface of the passage unit (4). The shield plate (53) is provided with a projection adjacent to the contact line and protruding from the contact line. The projection is fitted into the groove. The reservoir unit (71), the actuator unit (21), and the wiring member (50) are included in a range maintained between the two shield plates (53) with respect to the lateral direction of the passage unit (4).
