を盛り一Ｊ二げて絶縁層７を形成している。Structure of the conventional example and its problems A conventional planar heating element of this type was constructed as shown in FIGS. 1 to 3. That is, 1 is an insulating substrate, 2 and 2 are a pair of strip-shaped electrodes provided on the insulating substrate 1, and 3 is a heating resistor arranged so as to be twisted between the pair of strip-shaped electrodes 2, 2;
4 is a lead wire connected to the pair of strip electrodes 2.2;
5 is an insulating coating that covers the heating resistor 3. Reference numeral 6 denotes a connecting portion between the strip electrode 2 and the lead wire 4, and this connecting portion 6 is made of solder or conductive paint. The insulating layer 7 is formed by applying a layer of resin as shown in FIG.

工数のロスが大きいという問題点を有していた。However, the resin used for the insulating layer 7 in the above-mentioned conventional structure is often an epoxy-based or phosphor-based adhesive, and even if this adhesive is applied in a raised manner as shown in FIG. The problem is that the resin flows until it is completely cured, and when it is cured, the coating thickness of the insulating layer 7 becomes thinner, making it impossible to ensure insulation performance. Ta. Further, in this configuration, the planar heating element must be left alone until the resin hardens, resulting in a problem in that there is a large loss in processing man-hours.

である。Structure of the Invention In order to achieve the above object, the present invention provides an insulating coating at the connection portion between the strip electrode and the lead wire, and a cap that covers the insulating coating. According to this structure, Since the insulating coating material provided at the connection between the strip electrode and the lead wire is covered with a cap, the insulating coating material does not spread out and flow in a plane, and as a result, the insulating coating phase maintains a predetermined thickness. Because it is cured, electrical insulation and moisture proofing properties can be sufficiently ensured. Since the insulating coating is protected by a cap, it is now possible to process the planar heating element, for example, by adding a heat insulating material to it.As a result, it is no longer necessary to completely leave the insulating coating to harden as in the past. Not only does this save time, but it also reduces the loss of processing man-hours.

The lead wire 15 is connected by. The connecting portion 16 between the strip electrode 12 and the lead wire 15 requires insulation and moisture-proof treatment, but in one embodiment of the present invention, an insulating coating 17 and a cap 18 are provided around the connecting portion 16.
This ensures electrical insulation and moisture resistance. The insulating coating material 17 is made of epoxy adhesive, silicone adhesive, polyester adhesive, or urethane adhesive, and this adhesive is applied to the connecting portion 16 and its surrounding area. By covering with the cap 18, the adhesive constituting the insulating coating material 17 is prevented from flowing, and a reliable insulating layer is formed even after the adhesive hardens.

すぐれた特長を有するものである。Generally, the adhesive constituting the insulating coating layer 17 is applied to the strip electrode 12.
When applying the adhesive in a thick layer to the connecting portion 16 between the lead wire 16 and the cap 18, the convex surface of the raised adhesive and the concave surface of the inner wall of the cap 18 perfectly match. Therefore, air gets mixed into the cap 18. Also in the method of filling the gap 18 with adhesive in advance and then covering the connection part 16,
Since the viscosity of the adhesive needs to be high to some extent, the method of filling the adhesive becomes difficult, and as a result, air tends to get mixed into the cap 18. Therefore, if the cap 18 is not provided with the discharge hole 19, an air layer 21 will be formed within the cap 18 as shown in FIG. Failure to do so will result in abnormal insulation performance. However, in one embodiment of the present invention, since the cap 18 is provided with the insulating covering material 17 and the discharge hole 19 for the mixed air, the excess filler material and the mixed air are discharged to the outside. This has the effect that the insulating layer can be formed reliably. Since the cap 18 is provided with a notch 2Q through which the lead wire 15 is led out, there is no difference in level caused by the lead wire 15.
This allows the cap 18 to be brought into close contact with the insulating substrate 11. The material of the cap 18 is not limited to a resin molded product, and may be made of an inorganic electrically insulating material1. The insulating coating layer at the connection part with the electrode wire 1) is covered with a cap, so that the insulating coating material does not spread and flow on a plane, and as a result, the insulating coating 41 has a predetermined thickness. It is possible to ensure sufficient electrical insulation and moisture-proofing properties, and even during curing after the insulating coating material is installed at the connection part between the strip electrode and the lead wire. Since the insulating sheathing material is protected by a cap, it is also possible to process the planar heating element, for example, by adding a heat insulating material.9 As a result, there is no need to harden the insulating sheathing material as in the past. It has excellent features such as a simple structure and the ability to eliminate the complete leaving time and reduce the loss of the number of additions.
