に困難がある。If we take a look at the above-mentioned conventional techniques in which heaters are installed side by side, in all of them, the dielectric electrode is buried in a dielectric material in order to maintain insulation against high voltage between the discharge electrode and the dielectric electrode, and the embedding process is There are difficulties in For example, it is known from Document 4 that a dielectric material having a fired dielectric electrode on its surface is heat-press-bonded with another dielectric material. Regarding heaters, the heater is buried in the dielectric material on the side of the dielectric electrode (
Reference 3) and the method in which the heater is buried in the dielectric material in line with the dielectric electrode (Example 2 in Reference 5) have difficulties in forming and insulating the heater, and in addition, the heater is buried in the dielectric material side by side with the discharge electrode on the discharge electrode side. (Literature 50 Example 1) has difficulty in insulating the heater.

わない。As detailed in Reference 2, the mesh discharge electrode allows the applied voltage for discharge to be lowered. According to experiments, what used to be 4,000 to 5 ooo v, in the reticular form it is less than 20
An equivalent discharge occurs at 00 V. Therefore, the dielectric strength between the discharge electrode and the dielectric electrode can be lowered. On the other hand, since both the dielectric electrode and the electrical resistor are formed by printing, the thickness on the surface of the dielectric is extremely thin, allowing the heat-resistant insulating film to cover them without any gaps, and making it possible to adhere them with adhesive. Become. Even with such an insulating structure, the voltage applied to the discharge is extremely low as described above, so the insulation can sufficiently withstand long-term use, and there are no difficulties in processes such as embedding. Note that if the electric resistor is provided on the surface on the discharge electrode side, the electric resistor and the dielectric electrode must be separately insulated, which is not suitable for the purpose.

Since it consists of this electrical resistor and a heat-resistant insulating film that covers the dielectric electrode and adheres to it through an adhesive, the discharge electrode has a voltage lower than that of a normal wire-shaped, not mesh-shaped, and can be formed by printing. Sufficient insulation life can be obtained by simply covering the dielectric electrode and the electrical resistor with a heat-resistant insulating film via adhesive, and the insulation of the dielectric electrode and the electrical resistor from the discharge electrode are integrated. This has the effect of providing a simple adhesive structure.
