Provided is a resin composition having excellent weather resistance, in which occurrence of initial coloration, bleeding and blooming is suppressed. The resin composition is characterized by comprising, with respect to 100 parts by mass of (A) an olefin-based resin: 0.05 to 0.3 parts by mass of (B) a hindered amine-based light stabilizer; 0.05 to 0.3 parts by mass of (C) a benzoate compound represented by the following Formula (1); and 0.001 to 0.01 parts by mass of (D) a benzotriazole-based ultraviolet absorber represented by the following Formula (2): (wherein, R1 and R2 each 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) (wherein, R4 and R5 each independently represent, for example, a hydrogen atom; R6 and R7 each independently represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms; R8 and R9 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms).
