is covered first with a main insulating layer 2 and then with an auxiliary insulating layer 3.

ンフィルム１０．１１により形成されている。As shown in FIG. 2, the main insulating layer 2 is made of two glass cloths 8 on which a dispersion of tetrafluoroethylene-hexafluoropropylene copolymer is coated and dried on both sides to provide a moisture-impermeable film (not shown). 9, while the auxiliary insulating layer 3 is formed from two polytetrafluoroethylene films 10, 11.
上記各絶縁層２，３の末端はいずれも熱融着により密閉
されているが耐熱性接着剤を用いて接着密閉することも
できる。The ends of each of the insulating layers 2 and 3 are sealed by heat sealing, but they can also be sealed by adhesive using a heat-resistant adhesive.

膜を無機質材料の発熱素子との接触面側或いは補助絶縁
層との接触面側のいずれに設けてもよい。In addition, in this example, a moisture-impermeable film of fluororesin was provided on both sides of the inorganic material to form the main insulating layer, but in the present invention, a moisture-impermeable film of fluororesin was provided only on one side of the inorganic material to form the main insulating layer. In this case, the moisture-impermeable film may be provided on either the surface of the inorganic material in contact with the heating element or the surface in contact with the auxiliary insulating layer.
また、本実例においては各絶縁層はいずれも２枚のシー

こともできる。In addition, in this example, each insulating layer was formed from two sheets, but one wide inorganic sheet covered the heating element to form the main insulating layer, and then a wide organic sheet was used to cover the heating element. A single insulating layer may be used to cover the main insulating layer to form an auxiliary insulating layer, or each insulating layer may be formed using three or more inorganic sheet-like materials and three or more organic sheet-like materials.
本考案では無機質材料より成る主絶縁層を用いており、
無機質材料は機械的強度に優れ、さらに補助絶縁層で覆
われているので、主絶縁層が破れるのを防ぐことができ
る。This invention uses a main insulating layer made of inorganic material.
Since the inorganic material has excellent mechanical strength and is covered with an auxiliary insulating layer, it can prevent the main insulating layer from tearing.
また、本考案では主絶縁層の上に補助絶縁層を形成した
ので、水分は補助絶縁層で阻止され、主絶縁層にまで浸
入し得す、水中或いは湿潤状態においても絶縁不良を起
こすことなく使用できる。In addition, in this invention, since the auxiliary insulating layer is formed on the main insulating layer, moisture can be blocked by the auxiliary insulating layer and can penetrate into the main insulating layer without causing insulation defects even in water or in wet conditions. Can be used.
さらに、主絶縁層には無機質材料の片面或いは両面にフ
ッ素樹脂の不透湿性皮膜を設けているので、例え補助絶
縁層が破れても水分は不透湿性皮膜で阻止され、絶縁不
良を生ずるようなことはない。Furthermore, since the main insulating layer is provided with a moisture-impermeable film of fluororesin on one or both sides of the inorganic material, even if the auxiliary insulating layer is torn, moisture will be blocked by the moisture-impermeable film and insulation defects will not occur. Nothing happens.
これに対し、発熱素子を絶縁フィルムで被覆しただけの
従来の面状発熱体は絶縁フィルムが破れたり、水中或い
は湿潤状態で安定して使用することができなかった。On the other hand, in conventional planar heating elements in which the heating element is simply covered with an insulating film, the insulating film may be torn, and the heating element cannot be used stably in water or in a wet state.
本考案は上記のように構成され、無機質材料により主絶

縁層を被覆する最外層には更に補助絶縁層が形成されて
いるので電気絶縁はほぼ完壁で水中、湿潤状態において
も長期安定して使用し得る特徴を有する。The present invention is constructed as described above, and since the main insulating layer is formed of an inorganic material, it is relatively inexpensive, has high mechanical strength, and can prevent damage to the main insulating layer, and the main insulating layer contains fluorine. A moisture-impermeable resin film is provided, and an auxiliary insulating layer is further formed on the outermost layer covering the main insulating layer, so the electrical insulation is almost complete and it can be used stably for a long time even in water and in wet conditions. It has the characteristics that can be used.
また、絶縁層はいずれも耐熱性に優れた材料で形成され
ており、高温連続使用が可能である特徴をも有する。Furthermore, all of the insulating layers are made of materials with excellent heat resistance, and have the feature that they can be used continuously at high temperatures.
