An object of the present invention is extremely fiber wonder thin, again, includes a hydrophilic high cellulose nanofibers, to provide a large specific surface area porous material and to provide a method for easily producing his porous body at a low cost. Method for producing a cellulose porous body according to the present invention, in a mixed solution containing the cellulose nanofibers as a dispersion medium in the method of manufacturing a cellulose porous body having a step of freeze-drying, with an organic solvent which is the dispersion medium was dissolved in water and water mixing a dispersion medium, the concentration of the organic solvent in the mixed dispersion medium is 2 to 40 mass%, and the solid content of the cellulose nanofiber of the mixed solution from 0.001 to 5% by weight.
