To produce a spacer for a gas-insulated electrical apparatus using thermoplastic resin which can be easily recycled.
An insulation body 4 of the spacer 3 is divided into a plurality of layers (two layers illustrated) in the axial direction of a conductor 2. Each of the divided bodies 12, 13 is formed using the thermoplastic resin, and the divided bodies 12, 13 are integrally combined. By dividing an insulation body 4, the thickness of each of the divided bodies 12, 13 can be made small, thus enabling injection molding by the thermoplastic resin of each of the divided bodies 12, 13. These divided bodies 12, 13 are combined so as to be in a hollow shell condition, and partially or totally jointed by adhesion, fitting, or fusing, thus obtaining required mechanical strength and insulation strength.
