PROBLEM TO BE SOLVED: To obtain a polyolefin-based resin composition hardly discoloring even when exposed to UV light, or the like, and comprising a polyolefin and an esterified wood-based material. SOLUTION: A polyolefin-based resin composition comprises (A) a polyolefin, (B) an esterified wood-based material obtained by addition-esterifying a polybasic acid anhydride to hydroxyl groups in the wood-like material, and (C) a discoloration-preventing agent selected from the group consisting of hydrotalcite, sodium carbonate and calcium oxide. The discoloration-preventing agent is added in an amount of 0.05-10 pts.wt. per 100 pts.wt. of the total amount of the components A and B.
