Zusammenfassung:	To provide: a cellulose solution (a composition) in which decomposition of cellulose does not easily proceed even if it is heated; and a cellulose fiber production method for producing cellulose fiber excellent in mechanical strength.SOLUTION: The composition includes cellulose and a compound represented by the formula (1), where the concentration of 1-methylimidazolium chloride is 300 ppm or less on a mass basis with respect to the compound represented by the formula (1). In the formula (1), R is an alkyl group having 2 to 6 carbon atoms, and Me is a methyl group.SELECTED DRAWING: Figure 1 【課題】加熱してもセルロースの分解が進行しにくいセルロース溶液（組成物）を提供する。機械的強度に優れたセルロース繊維を製造するための、セルロース繊維の製造方法を提供する。【解決手段】セルロースと、式（１）で表される化合物とを含む組成物であって、１－メチルイミダゾリウムクロリドの濃度が質量基準で、式（１）で表される化合物に対し３００ｐｐｍ以下である、組成物。式（１）中、Ｒは、炭素数２～６のアルキル基であり、Ｍｅは、メチル基である。TIFF2023121836000009.tif25147【選択図】図１
