PROBLEM TO BE SOLVED: To reduce the dripping of a resin composition from a coil after dripping processing due to the low viscosity of the composition at a high temperature by using a fatty acid amide, to improve impregnation properties of the composition, to reduce the sticking of the composition to a core, to reduce the dripping amount of the electric insulating resin composition stuck to the core, and consequently to reduce the scraping work of the electric insulating resin composition. SOLUTION: The resin composition for electric insulation contains (A) a denaturation unsaturated epoxy ester resin of 10 to 95 weight part obtained by using an unsaturated epoxy ester resin produced by making an epoxy compound containing one or more epoxy group in one molecule react with anα,β-unsaturated monobasic acid and further making the compound react with the unsaturated acid anhydride, (B) a reactant monomer of 10 to 95 weight part and (C) a fatty acid amide of 0.01 to 30 weight part.
