Abstract: The objective of the present invention is to provide a method for easily and efficiently producing cellulose beads which have pore shape suitable for an adsorbent and of which adsorption performance is excellent without using highly toxic and highly corrosive auxiliary raw material and without industrially disadvantageous cumbersome step. The method for producing porous cellulose beads according to the present invention is characterized in comprising (a) the step of preparing a fine cellulose dispersion by mixing a low temperature alkaline aqueous solution and cellulose, (b) the step of preparing a mixed liquid by adding a crosslinking agent to the fine cellulose dispersion, (c) the step of preparing an emulsion by dispersing the mixed liquid in a dispersion medium, (d) the step of contacting the emulsion with a coagulating solvent.
