The present invention provides a resin composition for impregnating a coil that can be cured at a low temperature as compared with the prior art and has a long usable time after mixing with a curing agent. SOLUTION: (A) an unsaturated polyester resin, (B) a reactive monomer, (C) a low-temperature decomposable organic peroxide having a half-life of 10 hours and a temperature of 55 to 70 ° C., and a half. It can be cured at low temperature with a curing agent composed of two organic peroxides, a medium temperature decomposition type organic peroxide whose temperature is 85 to 100 ° C., and the pot life after mixing the curing agents Resin composition for long coil impregnation.
