PROBLEM TO BE SOLVED: To provide cellulose acylate which enhances brightness L* of a resin molded body when a resin composition containing obtained cellulose acylate is molded at high temperature, compared to a case in which a volume average particle diameter D50 measured using a laser diffraction type particle size distribution measuring apparatus is less than 10 μm or more than 100 μm.SOLUTION: Cellulose acylate has a volume average particle diameter D50 measured using a laser diffraction type particle size distribution measuring apparatus of 10 μm or more than and 100 μm or less.SELECTED DRAWING: None 【課題】レーザー回折式粒度分布測定装置を用いて測定した体積平均粒径Ｄ５０が、１０μｍ未満であるか、１００μｍを超える場合に比べ、得られるセルロースアシレートを含む樹脂組成物を高温で成形したときに、樹脂成形体の明度Ｌ＊が高くなるセルロースアシレートを提供することである。【解決手段】レーザー回折式粒度分布測定装置を用いて測定した体積平均粒径Ｄ５０が、１０μｍ以上１００μｍ以下である、セルロースアシレート。【選択図】なし
