PURPOSE: A waterproof frame type carbon paper heater panel having a function of displaying an operation state is provided to display the operation state with the change of a picture by printing two or more pictures on a base design. CONSTITUTION: A carbon paper(130) is cut in a square shape. An electrode(120a,120b) is composed of copper film or aluminum foil on two facing sides of the carbon paper. The electrode is superposed on the carbon paper. A heater(100a) is formed by thermal-compressing the upper and lower surfaces of the electrode over the heat-resistant temperature of a heat-resistant resin front plate and a heat-resistant resin rear plate after covering the upper and lower surfaces of the electrode with the heat-resistance resin front plate and the heat-resistance resin rear plate. |
