To provide a vehicular exterior component having a resin part formed with a polyolefin resin composite material in which the size of cellulose aggregate is sufficiently small, abd highly hydrophobic polyolefin resin and cellulose are integrated together with high uniformity, and also having improved mechanical strength.SOLUTION: A vehicular exterior component has a resin part formed with a polyolefin resin composite material that contains polyolefin resin, and cellulose of 10-150 pts.mass relative to the 100 pts.mass of the polyolefin resin, where an area of aggregate of the cellulose is less than 20,000 μm.SELECTED DRAWING: Figure 1 【課題】セルロースの凝集体のサイズが十分に小さく、疎水性の高いポリオレフィン樹脂とセルロースとが高度な均一性で一体化されたポリオレフィン樹脂複合材を用いて形成され、さらには機械的強度が向上した樹脂部を備える車両用外装部品を提供することを目的とする。【解決手段】ポリオレフィン樹脂と、該ポリオレフィン樹脂１００質量部に対して１０〜１５０質量部のセルロースとを含有し、前記セルロースの凝集体の面積が２０，０００μｍ２未満であるポリオレフィン樹脂複合材で形成された樹脂部を備える車両用外装部品。【選択図】図１
