いという問題があった。2. Description of the Related Art In a conventional heater for heating a surface, as shown in FIG. 4, a heater unit 23 having a tubing heater 22 laid on a surface of a heat conductive film 21 is attached.
It had a structure to unite. However, the heater having this structure includes a tubing heater 22 and a heat conductive film 21.
Is so large that there is a problem that temperature unevenness between the vicinity of the tubing heater 22 and other portions is large.

暖房の仕方も幅を広げることができる。In order to solve the temperature unevenness, a sheet heater in which a resistance heating element itself is formed into a layer has recently been proposed. By providing electrodes at both ends of the heating element, the sheet heater generates heat at all planar points, so that the heating element can be uniformly heated.
Furthermore, by using a planar heater that has special ceramics and carbon fibers as components, it is possible to provide not only conduction heat but also infrared radiation.
The way of heating can be widened.

出させることが出来なかった。However, since the sheet heater is electrically conductive as it is, it is necessary to take measures to prevent electric shock in the case of an apparatus that heats by contacting a person. Therefore, the entire sheet heating element must be covered with an insulating material. For this reason, the electrodes could not be partially exposed.

ヒータ性能の低下を引き起こす可能性があった。In addition, a method of covering the entire sheet heater with an insulating material after the wiring process to the heating element is considered. In this method, the insulating material is coated in a state where the surface heating element has been subjected to the wiring process in advance. Therefore, it is difficult to handle the planar heating element, and the heater performance may be deteriorated due to breakage or bending of the planar heating element.

A heating element having an electrode and a heating element covered with an insulating layer, wherein the heating element has an insulating material on at least a surface on which the electrode of the sheet heating element is arranged; An opening for wiring processing is provided on the side opposite to the above.

熱体の取り扱いが困難となり生産性が低下する。In a conventional electrode exposure operation of a planar heater, a wiring process is performed in advance from a heating element electrode portion, and if the surface of the heating element is covered with an insulating material so as to expose the wiring, the heating element may be broken. There is a possibility that heater performance may be degraded due to bending or bending. Further, since it is necessary to perform the covering work in a state where the wiring and the like are installed, it is difficult to handle the heating element, and the productivity is reduced.

り扱いが容易になるため、作業ミスが減少できる。In the present invention, the heating element may have an insulating material on the surface on which the electrodes are arranged, and an opening for wiring may be provided on a side of the electrode portion opposite to the insulating material. Accordingly, after the entire planar heater is covered with the insulating material, the wiring processing can be performed. Therefore, the number of man-hours for the wiring process can be reduced, and the handling of the planar heater is facilitated, so that the number of work errors can be reduced.

た。In the case where an opening is provided in the insulating material, the insulating material provided with the opening is coated on the heating element in advance, or the entire heating element is coated with the insulating material. A method of putting in a sharp edge with a knife or the like and peeling it off is considered. However, in the former case, it is difficult to position the opening and the electrode material, so that the productivity may be reduced. In the latter case, since the electrode material and the insulating material adhere to each other, it is difficult to perform the peeling operation. In addition, due to a work error, the insulating material and the electrode material may be damaged, and the sheet heater may be bent. For example, there is a possibility that the heater performance is deteriorated. Further, in a work process of coating the heating element with the insulating substance, the conductive fiber in the heating element may be scattered and directly attached to the electrode portion, so that the heater performance may be deteriorated.

生産性を向上することができる。The invention according to claim 2 is the method of manufacturing the planar heater, wherein a non-conductive thin leaf is previously provided on the surface of the electrode material opposite to the surface of the heating element to protect the electrode material, and then the heating element is formed. After coating with an insulating material, the insulating material and the thin body are cut and removed to form openings, thereby lowering the heater performance due to the work of exposing the surface heater electrode and the work of coating the heating element with the insulating material.
