摘要： An object of the present invention is to provide ultrafine fibrous cellulose capable of exhibiting excellent coating suitability when added to paint. The present invention relates to fibrous cellulose having a fiber width of 1,000 nm or less, in which, when the fibrous cellulose is dispersed in water to form a dispersion liquid having a viscosity of 2,500 mPa·s at 23° C., and the dispersion liquid is stirred under predetermined stirring conditions, a viscosity change rate falls within ±50%, calculated by the following formula: viscosity change rate (%)=(viscosity after stirring−viscosity before stirring)/viscosity before stirring×100.
