Vacuum valve and method for manufacturing same

A method for manufacturing a vacuum valve including a structure having:

• a container in which a fixed-side end plate and a movable-side end plate are fixed to both ends of an insulation cylinder;
• and an arc shield at an intermediate portion of the insulation cylinder, the method comprising:
• applying a material, in a liquid state, containing particles having a voltage nonlinear resistance characteristic at at least either one of an outer creepage surface or an inner creepage surface of the insulation cylinder, and curing the material, to form a voltage nonlinear resistance layer, such that
• a filling rate of the particles in the voltage nonlinear resistance layer has a distribution along a film thickness direction, and
• a filling rate of the particles in an outermost layer is not greater than half of an average filling rate of the particles in an entirety of the voltage nonlinear resistance layer.
