Provided is a resin composition which does not undergo the occurrence of initial discoloration, bleeding or blooming and has excellent weather resistance. A resin composition characterized by comprising (A) 100 parts by mass of an olefin resin, (B) 0.05 to 0.3 part by mass of a hindered-amine-type light stabilizer, (C) 0.05 to 0.3 part by mass of a benzoate-type compound represented by general formula (1), and (D) 0.001 to 0.01 part by mass of a benzotriazole-type ultraviolet ray absorber represented by general formula (2). (In general formula (1), R1 and R2 independently represent a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or the like; and R3 represents an alkyl group having 8 to 30 carbon atoms.) (In general formula (2), R4 and R5 independently represent a hydrogen atom or the like; R6 and R7 independently represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms; and R8 and R9 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.)
