And the anti-slip material 5 is provided. Reference numeral 11 is a temperature controller.

Next, the operation and effect of the above structure will be described. When the heat generation part 2 generates heat by operating the temperature controller 11, this heat is distinguished into heat that is transmitted through the surface material 1 and used for collecting heat and heat that is transmitted through the heat insulating material 3 and is transmitted to the floor surface. The amount of heat transmitted to the heat insulating member 3 can be reduced by the heat insulating property of the heat insulating material 3, and the electricity bill can be saved.
Since the first layer 3A of the heat insulating material 3 is made of anti-wool felt, the heat insulating effect can be enhanced and the cost can be reduced. Furthermore, the appearance may not be uniform only with the anti-wool felt of the first layer 3A, but by forming the second layer 3B with polyester felt and laminating it, it is possible to maintain the appearance and improve the heat insulating property. . Further, when the non-slip material 5 is provided on the floor surface side of the heat insulating material 3, that is, the lower surface, the non-slip material 5 itself enhances the heat insulating property, and when the surface heating tool 6 is laid on the floor due to high friction resistance. In addition, the anti-slip effect can be exhibited, and the strength of the lower surface of the heat insulating material 3 against fraying can be increased.

In the second embodiment of the heat insulating material 3, the first layer 3A is made of polyester hollow fiber felt, and the second layer 3B is made of polyester normal fiber felt. As described above, in the second embodiment of the heat insulating material 3, by using the polyester hollow fiber in which the fiber thread is hollow as the first layer 3A, it becomes a felt including an air layer and the heat insulating effect can be enhanced. . Furthermore, by stacking polyester normal thread felt as the second layer 3B, the air layer can be confined inside and the heat insulating effect can be further improved.

In the third embodiment of the heat insulating material 3, the first layer 3A is made of polyester thick denier ordinary thread felt and the second layer 3B is made of polyester fine denier ordinary thread felt. In addition, denier is a unit of a constant length formula that represents the fineness, and represents the weight per 9000 m in length in grams. As described above, in the third embodiment of the heat insulating material 3, the polyester thick denier ordinary yarn is used as the first layer 3A, whereby a soft heat insulating layer including an air layer can be formed to enhance the heat insulating effect. . Furthermore, by laminating polyester fine denier ordinary yarn as the second layer 3B, the air layer can be confined inside and the heat insulating effect can be further improved.

The present invention is not limited to the above-mentioned embodiment, and for example, as shown in FIG. 5, the ultrasonic welding portion 7A provided on the outer peripheral portion of the sheet-shaped warming tool 6 is arranged in a diamond shape. In order to improve the aesthetic appearance, and as shown in FIG. 6, a heat insulating material 3C having a slightly low heat insulating property is used as a surface material, and the heat insulating material 3C is made of different materials through the heat generating portion 2 and the adhesive layer 4.

In this case, the heat insulating material 3C is made of a material different from that of the first layer 3A and the second layer 3B or the first layer 3A.
The same material as either the layer 3A or the second layer 3B is used. Therefore, in this case, the heat insulating material 3C can also be used as the surface material.
