Abstract

PURPOSE:To improve the transfer rate of heat to thermal paper by using a system in which a polyimide film insulation plate is laminated on a cooling plate having a convexed portion in its portion touched by the thermal paper in such a way as to project the convexed portion on the surface of the thermal head. CONSTITUTION:A polyimide film insulation base plate 7 and a resistor heating body 8 are orderly provided on the surface of a cooling plate 6 made of aluminum plate, etc., having a convexed portion in its portion touched by a thermal paper, having excellent corrosion reistance and excellent heat conductivity. The resistor heating body 8 is made of a electroless Ni-based alloy plating, e.g., of Ni-P, Ni-B, Ni-W-P alloys. A power supplying body 9 for the resitor heating body 8 is formed by crystallizing out Ni, Cu, or Au by electrolytic method, and covered with a wear-resistant layer 10 formed by an alumina-based coating agent serving to prevent the oxidation of the heating body 8.
