PURPOSE:To obtain a high-speed, high-quality full-color printer at low cost by a method in which in a recording head consisting of a conductive layer, an insulator layer and a recording electrode, the base plate formed by providing the recording electrodes on an insulating base plate is bonded to a metal plate to form a common electrode. CONSTITUTION:In a recording head 20, a recording electrode pattern 24 is formed on an insulating base plate 21 of ceramics, etc., by vapor deposition and photo-etching techniques. A recording electrode material 25 is provided by a selective plating on the pattern 24 to form a base plate 22, and the base plate 22 so formed is bonded to a conductive plate 6 of a metal, etc. A high-density recording head can thus be obtained with a highly accurate photo-etching technique on a mass production basis. As the insulating base material having a heat resistance, alumina-based ceramics and SiO2 and MnO-based steatite and forsterite are suitable. As the recording electrode material having a wear resistance, materials having a high hardness and capable of being plated, e.g., Ni-P, etc., are recommendable. |
