Further, in the invention according to claim 2, since a mixture of rubber and asphalt is used as the protective layer, heat from the heating heater is applied to the protective layer made of the mixture of rubber and asphalt to form a linear layer. The rubber and asphalt mixture, which is transmitted from the surface, has a high thermal conductivity, so it can increase the snow melting heat efficiency and also has a load-bearing capacity, a buffering property,
Because of its high flexibility and flexibility, it is suitable for roof or road laying and can withstand the weight of snow and the weight of automobiles, and can be used durably. In addition, the surface of the protective layer becomes less slippery, which can prevent workers from slipping down during roof laying work and can suppress the snow from falling off the roof to enhance the snow melting effect. As a heat generating material for snow melting in snow melting parts such as roads and roads,
According to the third aspect of the present invention, since fine sand is contained in the protective layer, the surface of the protective layer becomes less slippery, thereby preventing a worker from slipping off during roof laying. In addition, in the invention according to the fourth aspect, since the far-infrared radiating substance is blended in the protective layer, the snow melting effect can be further improved. In addition, in the invention according to claim 5, since a soaking plate is disposed between the protective layer and the heating heater, when a plurality of heating heaters are arranged in parallel, Above a plurality of adjacent heaters, a heating plate can provide a snow melting effect.

As described above, the intended purpose can be sufficiently achieved.
