摘要： A method of producing a printer head wherein a substrate including at least one piezoelectric member polarized in its thickness direction is formed. A plurality of grooves and a plurality of posts are alternately defined in the substrate. A pre-processing solution is allowed to flow along the grooves at the following relative velocity so as to effect pre-processing when the velocity of the pre-processing solution for electroless plating relative to an object to be plated is V, the height of each of electrodes formed on the internal surfaces of the grooves is H, the width of each groove is W and a contact angle at which the pre-processing solution is brought into contact with the internal surfaces of the grooves is .theta..VW.sup.2 (1+cos.theta. )/H.sup.2 >0.6 mm/sThereafter, the substrate is immersed in an electroless plating solution to form the electrodes. A roof is joined to the surface of the substrate so as to close the top opening surfaces of the grooves, thereby defining a plurality of pressure chambers.
