る。The adhesive force between the base fabric and the heating element is stronger than that between the base fabric and the heating element, so if a load is applied or the heating element is repeatedly bent during use, the heating element There is a problem in that the resistance of the heating element fluctuates and becomes extremely unstable as a result of peeling off from the base fabric and causing cracks, or partial delamination of the heating element within its layers. In an attempt to eliminate this inconvenience, it has been considered to use a specific adhesive that can weaken the adhesive strength, but this would cause the protective insulating sheet to peel off easily, making it impossible to perform its original protective function. Without,
This too was not an appropriate measure. The present invention was devised in order to overcome the various problems that the conventional products have, and to solve these problems. The adhesive strength of the insulating sheet to the base fabric is increased by using a special material that has strong adhesive strength against the heating element and weak against the heating element, and also by specifying the arrangement of the heating element. However, it is possible to eliminate adverse effects such as peeling on the heating element, and to maintain stable heating performance and strengthen the protection function of the heating element.

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 schematically show a planar heating element according to one example of the present invention, which consists of a base fabric 1, a pair of charging electrodes 2, 2, and horizontal stripes arranged in parallel. It is formed of thin strip-shaped heat generating thin layers 3, 3, an inner insulating sheet 4 and an outer insulating sheet 5. The base fabric 1 is formed of a woven fabric selected from among natural fibers, man-made fibers, and synthetic fibers, for example, polyester fiber yarns. A pair of charging electrodes 2, which are integral with the base fabric 1, are continuously provided on the left and right sides by weaving thin threads with surface conductivity into a narrow band shape in the warp direction near both edges of the base fabric 1. However, as the fine thread,
For example, a polyester fiber thread of 100 to 250 deniers is used as a core, and a rectangular copper wire of 23 μm in thickness and 300 μm in width is wound spirally, but it is of course possible to use an extremely thin copper wire. By applying a conductive paint such as a fluororesin paint containing carbon powder to the base cloth 1 having the charged electrodes 2, 2, or by pasting a conductive thin film sheet, Heat-generating thin layers 3, 3 are formed between the charged electrodes 2, 2 and in parallel at a predetermined pitch P, in close contact with one side of the base fabric 1, with the surface of the base fabric 1 in between. In this way, the inner insulating sheet 4 is attached to the entire surface of the base fabric 1 on the side where the heat generating thin layers 3, 3 are in close contact, but in this embodiment, the base fabric 1 on the side where the heat generating thin layers 3, 3 are not present.
An inner insulating sheet 4 is similarly pasted on the entire surface. Then, an outer insulating sheet 5 is adhered as an outer covering layer over the entire surface of the inner insulating sheet 4 to form a planar heating element whose outer surface is protected by the insulating sheet. The inner insulating sheet 4 is a sheet with a thickness of about 30 to 40 μm, and is adhered to the surface of the base fabric 1 by heat fusion or adhesive bonding. It is necessary for the material to have adhesive properties to the heat generating thin layer 3, and to be able to maintain an adhesive surface that has no adhesive properties, or even if it does have it, it is extremely weak. The desired product can be obtained by specifying the sheet material in the case of touching and the adhesive in the case of adhesion. In the illustrated example, the base fabric 1 is made of polyester fiber, while the heat-generating thin layer 3 is made of carbon-based paint. Strongly adheres to the surface of the base fabric 1 and heat-generating thin layer 3
It can be brought into close contact with one side of the base fabric without adhesion. On the other hand, the outer insulating sheet 5 may be selected from a material that has good adhesion to the inner insulating sheet 4, and in this example, sheets made of polyester resin, vinyl chloride resin, etc. are preferred.
Note that 6 in FIG. 1 is a conductive wire drawn out from the charged electrodes 2, 2. In the planar heating element configured as described above, the inner layer insulating sheet 4 as a protective layer is formed by the band-shaped heating thin layers 3, 3.
Since the sheet 4 has almost no adhesive force and is easily separated, the sheet 4 does not receive any force in the direction of peeling the heat generating thin layer 3 from the base fabric 1, and the degree of adhesion between the two 3 and 1 is low. Moreover, since the inner layer insulating sheet 4 is strongly adhered to the base fabric 1 existing between the heat generating thin layers 3, 3, it is integrated with the base fabric 1 and does not peel off.

As described above, the present invention includes the heat generating thin layer 3 and the base fabric 1.
On the surface where and are repeated in alternating bands,
Since the inner insulating sheet 4 with good adhesiveness is adhered to the base fabric 1, the sheet 4 strongly adheres to the base fabric 1 and does not peel off, stably exhibiting its protective function. On the other hand, the heat generating thin layer 3 is easily separated from the inner insulating sheet 4 and is not affected by its movement, so there is no risk of it peeling off from the base fabric 1, interlayer peeling or cracking, and it is designed as a stable resistor. It is possible to generate heat for a long period of time.
