Abstract: According to an embodiment, an ink jet head includes a pair of actuator plates, a return plate, and a flow passage plate. The pair of actuator plates are disposed to face each other in a Y-direction. In the actuator plate, a plurality of channels which extend in a Z-direction are arranged at a distance in an X-direction. The return plate is disposed on an opening end side of the channels in the pair of actuator plates. A circulation passage which communicates with the channels is formed in the return plate. The flow passage plate is disposed between the pair of actuator plates. An inlet flow passage into which an ink flows and an outlet flow passage which communicates with the circulation passage are arranged in the Z-direction.

Abstract: According to an embodiment, an ink jet head (liquid ejecting head) includes an actuator plate and a cover plate (see FIG. 8). As illustrated in FIG. 1, channel grooves for a discharge channel (ejection channel) and a non-discharge channel (non-ejection channel) in a Z-direction are formed on a front surface of the actuator plate, so as to be alternately arranged in an X-direction, by cutting with a dicing blade or the like. The discharge channel and the non-discharge channel are formed to have a groove width W of smaller than 70 ?m, in order to correspond to high density of nozzles. In the embodiment, the discharge channel and the non-discharge channel are formed to have a groove width of 55 ?m, 50 ?m, or 40 ?m, for example.

Abstract: A discharge channel and a non-discharge channel are formed to have a similar shape, that is, to include extension portions and raise-and-cut portions continuing from end portions of both the extension portions, respectively. Then, imparting of a catalyst, washing of an unnecessary catalyst, plating, and the like are performed on a target surface, as a plating step. In an embodiment, an electrode clearance groove is formed after the plating step. Since channel grooves for the discharge channel and the non-discharge channel have a similar shape, it is possible to cause a water flow to uniformly flow in the channels when washing is performed, and thus to avoid an occurrence of a situation in which a lump is formed in the channel groove by plating.

Abstract: Channel grooves for a discharge channel and a non-discharge channel are formed in the surface of an actuator plate by cutting. The discharge channel includes an extension portion and a raise-and-cut portion, and the non-discharge channel also includes an extension portion and a raise-and-cut portion. In an embodiment, an electrode clearance groove is formed in advance by cutting with a dicing blade or the like. After the electrode clearance groove is formed, an electrode is formed by plating. Since plating is performed after the electrode clearance groove is formed, a clearance groove electrode is integrally formed with an AP-side common pad in the electrode clearance groove, and thus the clearance groove electrode and the AP-side common pad are short-circuited. Thus, an electrode separation portion is formed by cutting a short-circuited portion of the clearance groove electrode and the AP-side common pad through cutting or irradiation with laser.
