To provide an antifogging agent for polyolefin-based resin which exhibits antifogging property promptly after being molded and keeps antifogging property and transparency of a polyolefin-based resin for a long period of time, and a polyolefin-based resin composition including the antifogging agent.SOLUTION: The antifogging agent for polyolefin-based resin is provided that contains a glycerol fatty acid ester component (A), a component (B) which is an alkylene oxide adduct of polyvalent alcohol fatty acid ester, and at least one component (C) selected from an alkylene oxide adduct of aliphatic amine and aliphatic alcohol, wherein a ratio (OHv/Sv) of a hydroxyl value (OHv) to a saponification value (Sv) of the antifogging agent is in the range of less than 1.5.SELECTED DRAWING: None 【課題】成形後速やかに防曇性を発現するとともに、長期間にわたり防曇性とポリオレフィン樹脂の透明性を維持するポリオレフィン系樹脂用防曇剤、及びそれを含むポリオレフィン樹脂組成物の提供。【解決手段】グリセリン脂肪酸エステル成分（Ａ）と、多価アルコール脂肪酸エステルのアルキレンオキサイド付加物である成分（Ｂ）と、脂肪族アミンのアルキレンオキサイド付加物及び脂肪族アルコールから選ばれる少なくとも１種である成分（Ｃ）と、を含む防曇剤であって、前記防曇剤の水酸基価（ＯＨｖ）とケン化価（Ｓｖ）との比率（ＯＨｖ／Ｓｖ）が１．５未満の範囲にある、ポリオレフィン系樹脂用防曇剤。【選択図】なし
