Zusammenfassung:	To provide a resin composition with high whiteness and superior weather resistance imparted thereto, and a resin sheet.SOLUTION: A resin composition contains olefinic resin and calcium carbonate. The calcium carbonate particles have a particle size distribution (D90/D10) of 1-5 and an average particle size (D50) of 2-10 μm in volumetric frequency particle size distribution measurement.SELECTED DRAWING: None 【課題】高い白色度、及び優れた耐候性を付与した樹脂組成物、及び樹脂シートを提供する。【解決手段】オレフィン系樹脂と、炭酸カルシウムと、を含有する樹脂組成物であって、前記炭酸カルシウムの粒子が、体積頻度粒度分布測定において、粒度分布（Ｄ９０／Ｄ１０）の値が１～５であり、かつ平均粒子径（Ｄ５０）が２～１０μｍであることを特徴とする、樹脂組成物である。【選択図】なし
