摘要：
A metal including a passivation film 33a with a thickness of 10 nm or more is used as a metal electrode (a focus cup electrode 33) for generating an electric filed in a vacuum. The focus cup electrode 33 is made of stainless steel. The stainless steel is immersed in a treatment solution to perform coating (passivation treatment) . Accordingly, the passivation film 33a can be formed to be thicker than 10 nm. In this manner, the passivation film 33a is thicker than 10 nm. Therefore, the surface is uniform, and the adhesion is excellent, and the number of pinholes is small. Accordingly, the withstand voltage performance can be improved.
摘要（中）：
使用包括厚度为10nm以上的钝化膜33a的金属作为用于在真空中产生电场的金属电极（聚焦杯电极33）。 聚焦杯电极33由不锈钢制成。 将不锈钢浸入处理溶液中以进行涂覆（钝化处理）。 因此，钝化膜33a可以形成为比10nm厚。 以这种方式，钝化膜33a比10nm厚。 因此，表面均匀，粘附性优异，针孔数少。 因此，能够提高耐压性能。
