Ink jet recording head

Abstract

Abstract PURPOSE:To enable the production of a small-size recording head and a multi- nozzle and the reduction of production cost, by a method wherein an ink path, an ink cavity groove, an ink supply path groove, and an ink nozzle groove are provided in piezoelectric ceramic green sheets and electrodes are formed on predetermined portions and these sheets are successively laminated and calcined. CONSTITUTION:Respective plates are laminated in the order of a baseplate 28, an ink cavity plate 24, an ink supply path plate 21, and a cover plate 20 and thermocompression-bonded by carrying out a temperature sensing press under the conditions of a temperature of 60-120 deg.C and a pressure of 80-200 kg/cm<2>. The thermocompression-bonded laminate is inserted into an electric furnace and kept at 400-600 deg.C for several hours, whereby an organic binder contained in piezoelectric ceramic green sheets is removed. Thereafter, it is heated up to 1150-1250 deg.C and kept at this temperature for several hours, whereby the respective plates become an integral part and an ink jet recording head can be obtained.
