A flame-retardant soundproofing material for vehicles includes a polyurethane foam obtained by foam-molding a urethane resin composition. The urethane resin composition includes an isocyanate component (A), a polyol component (B), a flame-retardant plasticizer (C), and an antioxidant (D). The isocyanate component (A) includes a mixture of 2,4'-diphenylmethane diisocyanate and 4,4'-diphenylmethane diisocyanate, and one or more modified products selected from a carbodiimide-modified product and a uretonimine-modified product of at least one of 2,4'-diphenylmethane diisocyanate and 4,4'-diphenylmethane diisocyanate of the mixture.
