<P>PROBLEM TO BE SOLVED: To provide a non-conductive polymer material composition applicable to an insulation structure of high-voltage equipment, not only contributing to conservation of the global environment but also providing sufficiently good heat resistance, insulation properties, mechanical properties, or the like. Ž<P>SOLUTION: The non-conductive polymer material composition is obtained by heating and curing a non-conductive material comprising at least an epoxidized linseed oil and a curing agent and crosslinking the non-conductive material three-dimensionally. A rosin-originated curing agent chemically active to the epoxidized linseed oil is applied as the curing agent. The rosin-originated curing agent may be a product formed of a turpentine oil extracted by using a pine resin as a raw material, or a rosin (natural resin) consisting essentially of abietic acid, for example, a product obtained by subjecting the rosin to processing (hydrogenation or chemical modification).
