Abstract
A manufacturing method for an ink jet printer head, includes the steps of: cutting a plurality of channels for forming a plurality of ink chambers, on the upper surface of a substrate composed of a plurality of layers including at least one piezoelectric member polarized across its thickness; forming a pattern resist film covering a portion of the upper surface of the substrate except electrode forming portions on the inner surfaces of the channels and wiring pattern forming portions on the substrate; performing a process for adsorption of Pd on the electrode forming portions and the wiring pattern forming portions after forming the pattern resist film, for example, by performing a sensitizing process of adsorbing Sn on the substrate and next substituting Pd for the Sn, or by performing a catalyzing process of adsorbing a complex compound of Pd on the substrate and next performing an accelerating process of metallizing the complex compound of Pd; separating the pattern resist film; immersing the substrate from which the pattern resist film has been separated into a plating liquid for forming electrodes and wiring patterns; and mounting on the substrate a top plate and a nozzle plate to form the above ink chambers.
