［従来の技術］
従来、各種加熱板が知られているが、その一つに電気抵
抗による発熱を利用した加熱板がある。[Prior Art] Various types of heating plates have been known in the past, and one of them is a heating plate that utilizes heat generated by electrical resistance.

法としては、セラミック板中に電気導体を一体焼結して
埋設し、製造する方法が知られている。There are various methods for manufacturing heating plates that utilize electric resistance heat generation. For example, a sheathed heater in which an electric conductor and insulating powder are housed in a metal tube is placed on the back side of a metal plate by welding, or inside a metal root by an integral casting method. There is a way to manufacture it. Another known method is to sinter and embed an electric conductor in a ceramic plate.
［発明が解決しようとする課題］
しかしながら、前記シーズヒータを利用した加熱板は、
シーズヒータが金属管中に電気導体と絶縁物を内蔵させ
たものであるから、加工が難しく加工性に限界がある。[Problems to be Solved by the Invention] However, the heating plate using the sheathed heater has the following problems:
Since a sheathed heater has an electric conductor and an insulator built into a metal tube, it is difficult to process and there are limits to its workability.

出来ない。As a result, there is a problem that the shape of the back surface of the metal plate to which the sheathed heater is attached becomes complicated. Furthermore, since it is difficult to reduce the thickness of the sheathed heater, there is also the problem that it is difficult to reduce the overall thickness of the heating plate. Furthermore, since the sheathed heater requires a step of welding to a metal plate or casting, the manufacturing cost increases and the shape of the sheathed heater cannot be freely designed.

という課題がある。On the other hand, in the method of embedding an electrical conductor in a ceramic plate and sintering it integrally, in order to prevent the electrical conductor from melting in the ceramic plate, expensive metals such as molybdenum and tungsten, which are high melting point metals, are used. The production cost is high because ceramics have to be used and sintered in a high-temperature furnace, and because ceramics are brittle materials, the finished shape cannot be freely designed.
本発明は、この様な従来の電気抵抗利用の加熱板の課題

An electrical resistance heating element is formed on the insulating layer by thermal spraying, a second insulating layer is formed on the electrical resistance heating element, and the second insulating layer or the first insulating layer is formed on a metal plate. The above objective is achieved by bonding to the back surface.

誇張して描いである。In the figure, a metallic or resinous sheet l as a substrate is shown.
is a sheet made of metal such as steel plate, aluminum plate, alloy plate, or plastic material such as polyester. A first insulating layer 2 of an electrically insulating material such as Al2O3 or ZrO2 is formed on the layer 1. On top of that,
An electrical resistance heating element 3 made of a high resistance conductive material such as a Ni-Cr alloy is formed into a desired shape by a thermal spraying method. Furthermore, a second insulating layer 4 made of a material such as A I 203 or Z r02 is formed over the electrical resistance heating element 3 so as to cover it. Note that the dimensions of each layer of the heating plate shown in FIG. 1 are exaggerated to make the explanation easier to understand.
次に、本発明の上記実施例の加熱板を製造する方法を詳

ズマ溶射器６によって、マスキング板５上に溶射する。First, a metal or resin sheet 1 having a thickness of about 10011 m is plasma sprayed with Al2O3 having a particle size of 1 to 25 .mu.m to form a first insulating layer 2 having a thickness of about 10 to 50 .mu.m. By using fine powder with a particle size of that size, a more dense insulating layer can be made. Note that any thermal spraying method may be used, but plasma spraying is preferable because it uses high energy. Next, as shown in FIG. 2, a metal masking plate 5 having a long and narrow hole 51 of a desired shape is attached to the first masking plate 5. It is placed on the It layer 2, and the particle size l~
An electrical resistance heating element 3 made of a 25 μm Ni-Cr alloy or the like is thermally sprayed onto the masking plate 5 using a plasma sprayer 6 .

In this case, any solvent method may be used, but plasma spraying is preferable because it requires high energy. Thereafter, when the masking plate 5 is removed, a laminated plate as shown in FIG. 3 is obtained. That is, the electrical resistance heating element 3 having the shape of the elongated hole 51 is formed on the first insulation N2. Here, since the elongated hole 51 of the masking plate 5 can be manufactured into any sharp curved shape, the electrical resistance heating element 3 formed by plasma spraying can also be formed into a desired shape. I can do it.

By appropriately moving the plasma sprayer 6, it is also possible to directly spray the first insulating layer 2 and form it into a desired shape. The desired shape can be designed based on the amount of current and the amount of heat required. In this way, it becomes possible to produce a heating plate with a uniform temperature distribution for each section.

By plasma spraying fine powder, a second insulation F74 having a thickness of about 10 to 501 LW is formed so as to cover the electric resistance heating element 3. Next, as shown in FIG. 4, a heat-resistant adhesive 7 is applied to the metal plate 8 and adhered to the second insulating N4 side of the heating plate. Thereafter, as shown in FIG. 5, the resin sheet 1 is peeled off. Note that if the sheet 1 is made of metal, it is not necessary to peel it off.

。Furthermore, as shown in FIG. 6, the metal plate 8 may be adhered to the seam 1 side with an adhesive 7. In this case, even if the sheet 1 is made of resin, there is no particular problem as long as the heating plate is used within the heat resistance temperature of the resin sheet.

As a result, a heating plate having a uniform temperature distribution can be easily manufactured. In addition, since the electrical resistance heating element can be attached to the back side of the metal plate by a simple method of joining the insulating layer and the metal plate,
