To provide an electrical equipment insulating resin composition capable of significantly reducing volatile organic compounds (VOC) generated in an electrical insulating step and having a higher flash point than a curing temperature, excellent safety and such a high thermal conductivity that higher heat dissipation of electrical equipment can be expected, and to provide electrical equipment using the same.

The electrical equipment insulating resin composition is characterized in that when the electrical equipment insulating resin composition essentially containing a thermosetting resin and an inorganic filler is applied to electrical equipment and the electrical equipment is electrically insulated by curing the resin composition by heating, in the step of curing by heating at 130°C for 1 h, the electrical equipment insulating resin composition has a mass reduction rate of ≤5% and shows a thermal conductivity of ≥0.5 W/m K. The electrical equipment is electrically insulated by an electrical insulating method using the electrical equipment insulating resin composition.
