Zusammenfassung:	To provide a modified cellulose fiber formed from a biodegradable component and useful as a reinforcing material for resin.SOLUTION: A modified cellulose is prepared by modifying a cellulose fiber with 3-hydroxybutyric acid or an oligomer thereof. In the modified cellulose, the 3-hydroxybutyric acid or oligomer thereof may be ester-bonded to the 6-position of the anhydroglucose unit of the cellulose fiber. The 3-hydroxybutyric acid or oligomer thereof may have an average degree of polymerization of 1 to 10. The grafting rate of the 3-hydroxybutyric acid or oligomer thereof may be 5 to 30 mol%. The 3-hydroxybutyric acid may be R-3-hydroxybutyric acid.SELECTED DRAWING: None 【課題】生分解性成分で形成され、樹脂に対する補強材として有用な変性セルロース繊維を提供する。【解決手段】セルロース繊維に、３－ヒドロキシ酪酸またはそのオリゴマーが変性した変性セルロースを調製する。前記変性セルロースは、前記セルロース繊維の無水グルコース単位の６位に、前記３－ヒドロキシ酪酸またはそのオリゴマーがエステル結合していてもよい。前記３－ヒドロキシ酪酸またはそのオリゴマーの平均重合度は１～１０であってもよい。前記３－ヒドロキシ酪酸またはそのオリゴマーによるグラフト化率は５～３０モル％であってもよい。前記３－ヒドロキシ酪酸はＲ－３－ヒドロキシ酪酸であってもよい。【選択図】なし
