点があった。Problems to be Solved by the Invention However, in Japanese Patent Publication No. 49-7534, since the contact surface between the cord-shaped heating element and the metallic thin plate-shaped body (metal thin plate) is 20% or less, The heat transfer efficiency to the body (metal thin plate) is poor, and the cord-shaped heating element and the metallic thin plate-like body (metal thin plate) are joined by welding in a small area with a thin adhesive and thermoplastic resin layer. This may result in areas with insufficient adhesion, and if local overheating occurs in these areas, the cord-shaped heating element may become attached to the thin metal plate (
They have disadvantages such as detachment from the thin metal plate (thin metal plate), poor adhesion reliability during long-term use, and the use of non-softening insulators such as silicone rubber, making them expensive.

ニットを得る。In this embodiment, the cord-shaped heating elements 1 are arranged in a meandering manner so that the pitch is 30, and are bonded under heat at 180° C. for 2 seconds to bond the heat-fusible covering 4 of the cord-shaped heating elements 1 to the metallic thin plate-like body. After welding the heat-sealing thin body 6 provided on one side of 5,
The thin metal plate 5 is surrounded and integrated with the surface of the cord-shaped heating element 1 under a pressure of ffl, and the dispersion base 7 is stacked on the heat-sealing thin body 6 side and thermocompression bonded to form a heater. Get units.

Since the cord-shaped heating element 1 is surrounded and integrated with the outer periphery of the cord-shaped heating element 1 and is integrally bonded to the diffusion base 7 in close contact with it, the heat generated from the cord-shaped heating element 1 is efficiently transferred to the metallic thin plate-shaped body. 5 and diffusion substrate 7.

状発熱体１が固定部位からはずれることかなくなり１局
部過熱を起さない。In addition, since the metal thin plate-like body 5 and the diffusion base 7 mechanically enclose and fix the cord-shaped heating element 1, the cord-shaped heating element 1 does not come off from the fixed part, thereby preventing local overheating. I won't wake you up.
本発明に使用するコード状発熱体１け、金属性薄板状体
５により包囲一体化され易い為に、外径を１．８〜３．
０閣とし、最外かぐの熱融着性被覆体４はゴム硬度で５
０〜１２０の硬さが適する。Since the single cord-shaped heating element used in the present invention is easily surrounded and integrated by the thin metal plate 5, the outer diameter is set to 1.8 to 3.
The outermost heat-adhesive coating 4 has a rubber hardness of 5.
A hardness of 0 to 120 is suitable.
熱融着性被覆体４の硬さかゴム硬度で１２０を越えると
、金属性薄板状体５が加圧成形される際に加圧力が集中
してアルミ箔が切れてしまい、硬度が５０未満の場合は
熱融着性被覆体４の変形が大きすぎてアルミ箔が加圧成
形されにぐい。If the hardness of the heat-adhesive coating 4 or the rubber hardness exceeds 120, the pressing force will be concentrated when the metal thin plate-shaped body 5 is pressure-formed and the aluminum foil will break, and if the hardness is less than 50. In this case, the deformation of the heat-fusible covering 4 is too large, making it difficult to press-form the aluminum foil.
従って、熱融着性被覆体４の硬さはゴム硬度で５０〜１
２０．より好ましくは６０〜１００の硬さがよい。Therefore, the hardness of the heat-fusible covering 4 is 50 to 1 in terms of rubber hardness.
20. More preferably, the hardness is 60 to 100.

けた構造が適する。The material of the heat-fusible covering 4 is a material 9 that has both insulating and welding properties, for example, a tubing made of a thermoplastic nidistomer made of ethylene propylene resin and ethylene propylene rubber, or a material made of vinyl chloride. A structure in which an insulating layer is provided and a heat-fusible covering 4 made of a material such as polyethylene, vinyl acetate, or thermoplastic elastomer is provided is suitable.

A thickness of mm is good.
厚みが０．０３ｍｍより薄くなると加圧成形時に切れて
しまうことと、熱の拡散特性か低下するし、厚みが０．
２１より厚くなると、加圧成形しにくくなってコード状
発熱体１と包囲密着しにくい。If the thickness is less than 0.03 mm, it will break during pressure molding and the heat diffusion properties will deteriorate.
If it becomes thicker than 21, it will be difficult to press-form it and it will be difficult to encircle and closely contact the cord-shaped heating element 1.
従って、金属性薄板状体５の厚みは０．０３〜０．２削
、より好ましくはＱ、０５〜０．１ｍｍが適する。Therefore, the thickness of the thin metal plate 5 is suitably 0.03 to 0.2 mm, more preferably Q, 05 to 0.1 mm.
次に、コード状発熱体１と金属性薄板状体５と固定する
熱融着薄状体６は、熱圧着により溶融して熱融着性被覆
体４と溶着する。Next, the heat-sealing thin body 6 fixed to the cord-shaped heating element 1 and the metal thin plate-like body 5 is melted by thermocompression bonding and welded to the heat-fusible covering body 4 .

する。When performing pressure molding, the cord-shaped heating element 1 side is set as a hard surface,
Pressure is applied to the metal thin plate-like body 5 side through an elastic body. A metal thin plate-like body 5 extends along the outer peripheral surface of the cord-like heating element 1. As the elastic body used at this time, rubber having an expansion rate of 5 to 20 times is suitable.
