PROBLEM TO BE SOLVED: To provide a heating device to remarkably reduce a newly-arranging cost and a maintenance cost compared with a conventional air-conditioner type heater used for heating of a room and simplify post-mounting in a case of both existing and newly-arrangement, and be advantageous in various points. SOLUTION: Through connection to an indoor wiring, a heat source panel 10 is energized to generate heat. The heat source panel 10 has an electrode pattern 12 formed on a resin film 11 of a heat resistant material, and a PTC characteristics ink layer having a self-temperature control function is formed on the electrode pattern 12. The whole of a structure is supported by a frame- shaped decoration frame 2, and the decorated frame 2 is fixed at a ceiling board 5 by lock screws 6. A surface layer sheet 3, the heat source panel 10, and a heat insulation panel 4 are arranged in the order at the inside of the decorated frame 2. The positive and negative electrode terminals of the electrode pattern 12 are connected to a joint box 17 through lead wires 15 and 16 and connected to an indoor wiring through the joint box 17. |
