Abstract:
A process for producing an ink-jet recording head, comprising the steps of:forming a solid layer in a space for forming a liquid path and a part of a liquid chamber on a first supporting member having thereon a discharge pressure-generating element used for discharging an ink;forming an opening portion at a position for forming an ink-supply opening in a second supporting member;placing the second supporting member above the first supporting member;providing a curable or thermoplastic resin for forming walls of the liquid path and the liquid chamber onto the first supporting member so that the solid layer formed on the first supporting member is covered with the resin;curing the resin in such a state that the resin is interposed between the first and second supporting members;cutting from above the cured resin of the opening portion formed in the second supporting member until the solid layer to form an ink-supply opening and at least a part of a common liquid chamber; andremoving the solid layer to form the liquid path defined by the first supporting member and the resin.
