摘要： An object of the invention is to provide a material comprising ultrafine cellulose fibers, having good dispersibility of fine particles in an aqueous medium containing ultrafine cellulose fibers. According to the invention, there is provided a material comprising ultrafine cellulose fibers, wherein the content of the ultrafine cellulose fibers is 80% by mass or more, and the haze value of a sample, which has been prepared by adding the material comprising ultrafine cellulose fibers to pure water to a solid concentration of 0.4% by mass, and stirring the mixture with a disperser under conditions of 1500 rpm and 5 minutes, is 20% or less.
