Formed on a surface of an oscillation plate on the side of a head main body portion is an intermediate layer having a window portion through which a displacement portion of the oscillation plate is exposed to a pressure chamber. The intermediate layer and a compartmenting wall of the main body portion are adhered together by an adhesive of electro-deposition resin. The intermediate layer is formed of copper, having a thickness of 5 &mgr;m, so that, when a part of the adhesive is forced out, such a forced-out adhesive portion will not adhere to the displacement portion of the oscillation plate.
