To provide an adsorbent having excellent adsorptivity of a substance which causes malodor.SOLUTION: There is provided an adsorbent composed of a modified cellulose fiber, wherein a cellulose molecule constituting the modified cellulose fiber has a primary amino group and the modified cellulose fiber has an average fiber diameter of 2 to 1000 nm. The modified cellulose fiber contains lignin and the lignin is preferably modified with a nitrogen-containing compound having a primary amino group.SELECTED DRAWING: None 【課題】悪臭の原因となる物質の吸着性能に優れた吸着材を提供することを目的とする。【解決手段】変性セルロース繊維からなる吸着材であって；前記変性セルロース繊維を構成するセルロース分子が１級アミノ基を有し、かつ前記変性セルロース繊維の平均繊維径が２〜１０００ｎｍであることを特徴とする吸着材。このとき、前記変性セルロース繊維がリグニンを含み、該リグニンが１級アミノ基を有する含窒素化合物で変性されたものであることが好ましい。【選択図】なし
