PURPOSE: To provide the resin composition not causing the cissing of a coated film, having a smooth appearance, good in porosity, effective for improving the rate for covering processing flaws and pine holes on the coating films of electric wires, and capable of producing highly reliable electric equipments.

CONSTITUTION: A resin composition for electric insulation comprises (A) 5-70 pts.wt. of an epoxyacrylate resin, (B) 95-30 pts.wt. of an unsaturated polyester resin modified with 5-30wt.% of a thermoplastic polyester resin, (C) a reactive monomer, and (D) an inorganic filler as essential components, wherein the reactive monomer (C) and the inorganic filter (D) are compounded in amounts of 40-300 pts.wt. and 20-80 pts.wt., respectively, per 100 pts.wt. of the resin components [(A)+(B)]. An electric equipment is produced by impregnating the resin composition and subsequently curing.
