PURPOSE:To make installation of a partial glazed part needless and to achieve reduction of cost by making preparation by forming a heating resistor on an end slant of a plane glazed part. CONSTITUTION:Only a plane glaze 7b is formed on a surface of a ceramic substrate 1 in a thermal recording head composed of the ceramic substrate 1 which has heating resistor elements 2 and wiring electrodes 6 heat sink, driver IC3, and FPC4, and the heating resistor elements 2 are formed on an end slant of this plane glaze 7b. Since a thin film pattern is thus formed on the end slant of the plane glazed part, the thin film pattern can be prevented from generation of defective inferiority owing to its contact with a photomask. Further, since the thin film pattern is formed not directly on the ceramic substrate 1, defective inferiority of the thin film pattern can be prevented. Preparation of the thermal recording head can be made easy thereby, and reduction of its printing cost can be reduced. |
