A fine-cellulose-containing complex comprising 60 to 80 wt % of fine cellulose, 2 to 12 wt % of locust bean gum, 0.5 to 8 wt % of xanthan gum and 0 to 37.5 wt % of a hydrophilic material(s), the complex being a powder wherein the average particle size of particles formed by mild dispersion of the complex in water at 85.degree. C. is 60 .mu.m or less, the proportion of particles with a particle size of 100 .mu.m or more among the formed particles is 30 vol % or less based on the total volume of the formed particles, and a colloid fraction in the case of vigorous dispersion of the complex in water at 25.degree. C. is 30% or less.
