Generally, a heat-transfer sheet 100 which generates heat by electric conduction and is capable of heating constitutes an upper sheet 110 and a lower sheet 120 which is fitted under the upper sheet 110 . And heating lines 131 and 133 which are disposed between the upper sheet 110 and the lower sheet 120 and generate resistance heat by electrical conduction. The heating lines 131 and 133 are made of carbon yarn, for example.

As shown in FIG. 5, the heat transfer sheet 100 includes a plurality of heating lines 131 connected to a positive power source, and one end of the heat transmission sheet 100 is surrounded by the conductive tape 141 to be electrically connected. In addition, a plurality of the heating lines 133 connected to the negative power source are arranged side by side, and one end portion is surrounded by the conductive tape 143 to be electrically connected.

4, the heating sheet 131 connected to the positive power source and the inner sheet 150 are covered below the conductive tape 141. The heating sheet 133 connected to the negative power source and the conductive sheet 143 The inner sheet 150 is covered. The opposite end portions of the heating wires 131 and 133 connected to the positive power source and the negative power source, which are not connected to the conductive tapes 141 and 143, are configured to be surrounded by one conductive tape 145 and electrically connected thereto.

The upper and lower sheets 110 and 120 cover the conductive tapes 141, 143 and 145 and the heating lines 131 and 133 in the upper and lower walls.

As the conductive tapes 141, 143, and 145, for example, a silver foil tape is used in which electricity is applied to the inner side coated with an adhesive and electricity is prevented from flowing to the outer side.

The upper sheet 110, the lower sheet 120, and the inner sheet 150 may be made of a film, fabric, or the like, and preferably have heat resistance.

In order to increase the tensile strength of the heating lines 131 and 133 in the above-described constitution, the tension lines 160, which are wire materials superior in the tensile strength to the heating lines 131 and 133, So as to be wired in close contact with each other. Or may be twisted as shown in Fig.

Also, the heating lines 131 and 133 may be coated while being in tight contact with the tension lines. Therefore, the tensile strength is further increased due to the coating. At this time, portions of the conductive tape 141, 143, and 145 that are connected to the conductive tape 141 are peeled off.

Accordingly, when the positive power source and the negative power source are applied to the heating lines 131 and 133, the conductive tape 141, the heating line 131, the conductive tape 145, the heating line 133, Current flows to generate resistance heat in the heating lines 131 and 133.

As the tensile wire 160, heat resistant materials such as glass wool and Teflon can be used. In fact, since the temperature is limited to 50 ° C to 60 ° C, poly-synthetic resin, nylon, and general yarn can also be used.
