A cellulose dope comprising an aqueous sodium hydroxide solution and cellulose dissolved in the solution, wherein the cellulose dope has a sodium hydroxide concentration (C.sub.Na) of from 6.5 to 11% by weight, a cellulose content (Cc) of from 5 to 10% by weight, a viscosity average degree of polymerization (DPc) of the cellulose of from 350 to 1,200 and a cellulose dissolution ratio (Sc) of 99.0% by weight or more, and wherein the zero-shear viscosity (.eta..sub.0) and the cellulose content (Cc) of the cellulose dope and the viscosity average degree of polymerization (DPc) of the cellulose in the cellulose dope satisfy the following formula (1): .eta..sub.0=kCc.sup.m.times.DPc.sup.p (1) wherein: .eta..sub.0 represents the zero-shear viscosity (mPas) of the cellulose dope, Cc represents the cellulose content (% by weight) of the cellulose dope, DPc represents the viscosity average degree of polymerization of the cellulose in the cellulose dope, k=3.9.times.10.sup.-11, m is a number of from 5 to 7, and p is a number of from 3 to 4.
