ABSTRACT:
A process for producing an ink-jet head having an ink discharge opening for discharging an ink, an ink flow path communicating with the ink discharge opening, a liquid chamber communicating with the ink flow path for supplying the ink thereto, an energy-generating element for generating energy to be utilized for discharging the ink, and a metallic base plate provided with the energy-generating element is disclosed. The process comprises the steps of providing a metallic base plate having thereon a plurality of the energy-generating elements, forming, on the base plate, a plurality of ink flow path walls from a resin for forming the plurality of ink flow paths and the liquid chambers, bonding a ceiling plate onto the ink flow path walls, cutting the formed laminate of the metallic base plate and the ceiling plate having the ink flow path walls interposed therebetween into a plurality of laminate pieces, and immersing into a chemical treatment solution at least an end portion having that cut face of the cut faces of the respective laminate pieces which forms an ink discharge opening surface having the discharge opening formed therethrough.
