PROBLEM TO BE SOLVED: To provide a filament carbon heating element improving thermal efficiency without generating excess energy consumption, and to provide a planar heating element disposed with this. SOLUTION: The filament carbon heating element 1 is formed by winding a carbon resistor 2 comprising a freely deformable carbon fiber thread on an elastic wire 3 and further coating the whole with an insulating coating material 4 such as a resin having flexibility. Further, the planar heating element 7 is formed by meandering and disposing the filament carbon heating element 1 on a planar member. COPYRIGHT: (C)2011,JPO&INPIT
