PROBLEM TO BE SOLVED: To provide a lightweight and thin film, and to impart flexibility by forming a heat source of a flexible thin leaf body. SOLUTION: A heating element 2 is a flexible thin leaf-shaped sheet-like heater such as a paper-like heater, and when a power cord 6 is inserted into an electric outlet, an electric current is carried to the heating element 2 through an electrode 3. The heating element 2 starts heating so that heat from the heating element 2 is transmitted to insulating layers 4, 5. The heating element 2 is a sheet-like heating element by combining natural pulp and carbon graphite as Japanese paper. When the insulating layers 4, 5 are thinned to the possible minimum level in a range where dielectric strength satisfies a standard of an electric appliance regulating law, the rise of a temperature is quickened, and flexibility can also be enhanced. In this case, a shape can be three-dimensionally changed according to a shape of a heating object and a purpose of heating to thereby provide a lightweight, thin-film flexible heating system. |
