Abstract

PURPOSE:To obtain a high a quality thermosensitive recording head in terms of cost, and capable of high image quality recording free from color irregularity by increasing the width of a common electrode formed between a substrate and a heat insulation layer and reducing the resistance value of the common electrode through the decreasing of the resistance value of the common electrode. CONSTITUTION:A metallic membrane is provided on an alumina substrate 1 and this membrane is used as a common electrode 10. On the common electrode 10, a heat insulation layer 2 of heat resistant resin is provided on one side of the substrate 1 except and end 1A side. On the heat insulation layer, a plurality of thermal resistors 4 are aligned at a prearranged interval. In addition, drive-side electrodes 6 and common-side electrodes 8 are provided on the upper surface of the thermal resistor 4 to supply electric power to the thermal resistor 4. Further, the plurality of the common-side electrodes 8 are connected electrically to the common electrode 10 on the end 1A side of the substrate 1. The upper surfaces of the thermal resistors 4, the drive-side electrodes 6 and the common-side electrodes 8 are covered with a protection layer 12.
