Therefore, the formation of a gap between the second metal member 35 and the solid dielectric plate 50 can be reliably prevented, and the occurrence of arcing between the two can be reliably prevented.
- the first metal member 34 is a solid dielectric plate 5 Since the first metal member 34 can be stagnant and deformed independently of the second metal member 35 because the first metal member 34 is in direct contact with 0, no thermal stress is transmitted to the second metal member 35. Therefore, even if the first metal member 34 of the electrode 90 is stagnantly deformed, no gap is formed between the solid dielectric plate 50 and the electrode 90, and arcing does not occur between the two. There is no problem at all.
- the second metal member 35 protrudes slightly in the width direction from the first metal member 34, the arc is prevented from flying from the end in the width direction of the first metal member 34. Can.

- the thickness of the second metal member 35 is set according to the thermal conductivity of the material, and has a size such that the temperature difference between the upper surface and the lower surface due to heating at the time of plasma discharge is approximately 1 ° C. or less. Therefore, when using a material whose thermal conductivity is smaller than that of aluminum as the second metal member 35, the thickness is made smaller. For example, in the case of stainless steel, the thickness of the second metal member 35 is approximately 0.5 to 0.5 mm.
