Abstract
An ink jet head has a plurality of ink pressure chambers defined therein and a surface to which a plurality of ink pressure chambers open. An orifice plate having an orifice therein is bonded to the surface. When manufacturing the ink jet head, a coating of an insulating material is first formed on an inner wall of the ink pressure chambers and subsequently a re-dissolvable curingresin is applied to the ink jet head in an area from the inner walls to the surface. Then, the coating and the resin deposited on the surface are removed from the surface. Then, the resin deposited on the coating in the ink pressure chambers is dissolved to remove the resin from the inner wall. Finally, the orifice plate is bonded to the surface.
