PROBLEM TO BE SOLVED: To provide an impregnating resin composition which shows a good solderability at an impregnated, coated state and retains conventional electrical and mechanical properties and curability at a good balance, and an electrical appliance. SOLUTION: This impregnating resin composition essentially comprises (A) a tolylene diisocyanate-modified unsaturated polyester and (B) a polymerizable monomer, wherein 20 to 50 wt.% tolylene diisocyanate is contained in (A) the toylene diisocyanate-modified unsaturated polyester, and (B) the polymerizable monomer is blended at a proportion of 60 to 150 pts.wt. against 100 pts.wt. tolylene diisocyanate-modified unsaturated polyester. Furthermore, an electrical appliance is impregnated with the resin composition.
