摘要： A vacuum valve includes: a cylindrical vacuum insulation container 1 made of alumina porcelain; sealing metal fittings 2 and 3 which seal openings at both ends of the vacuum insulation container 1; and a pair of connectable and separable contacts 5 and 6 housed in the vacuum insulation container 1. The vacuum insulation container 1 has a base material layer 1c of alumina oxide and oxidation enhancement layers 1a and 1b disposed on inner and outer peripheral surfaces of the base material layer 1c by reheating and in which oxygen binding is enhanced. In the oxidation enhancement layers 1a and 1b, an oxygen defect portion deficient in the oxygen binding is repaired, and electrostatic charge is suppressed.
