Then, heat-sensitive heating wires H, which have a heat-fusible resin layer such as low-density polyethylene formed on the surface of the outermost layer, are wired in a predetermined pattern and molded into one piece by heating and pressurizing. Those equipped with A and back material B are generally known. As shown in FIG. 5, this type of planar heating element has heat-sensitive heating lines H arranged in a predetermined pattern on a heat-uniforming sheet made of a metal foil 2 with heat-fusible resin layers 1, 1 formed on both sides. Since it is wired, it has the advantage that the heat generation temperature is uniform over the entire surface and the temperature control moving body is stable.

美感が損なわれるという問題点を有している。 However, with conventional sheet heating elements, when finishing an electric carpet as shown in Figure 4,
When the surface material A and the back surface material B are bonded to both sides by heat press, the metal foil 2 of the heat-uniforming sheet C stretches due to thermal expansion, while the heat-sensitive heating wire H is extruded, so it is heated. The metal foil 2 of the heat-uniforming sheet C acts as a heat shrinkage effect, and also heat shrinks on the surface material A and the back surface material B.
Large ``deflections'' and large ``wrinkles'' occur mainly in the direction intersecting the wiring direction of the heat-sensitive heating wire H, which makes it uncomfortable to sit on and impairs the aesthetic appearance of the surface. There is.

ある。 In addition, when using an electric carpet, there will be a partially strong cross-sectional state, and the temperature of the sheet heating element will increase from 80 to
The temperature may rise to 90℃, and if exposed to high temperatures for a long time, the thermal expansion of the metal foil 2 of the heat-uniforming sheet C and the thermal contraction of the heat-sensitive heating wire H will result in large "deflections" and large " There is a risk of "hoe" occurring.
