An object of the present invention is to provide a method of manufacturing an insulating member for a gas-insulated device having a sufficient insulating performance. In an insulating member for a gas insulated device composed of an insulating material covered with a material, after the insulating material is cured, the surface is degreased, heated and dried, and the surface is further coated with the insulating material. Preferably, Vacuum heating and drying, in which vacuuming is performed simultaneously with heating and drying, is performed, and the heating temperature range is from 50 ° C. to the glass transition temperature of the insulator. |
