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.
