Abstract: The present invention provides a technique for preparing a porous cellulose medium, through the gelation of a solution in which cellulose acetate as a raw material is dissolved, which does not cause a reaction involving the migration of substances. Specifically, a method for producing a porous cellulose medium is provided which includes the steps of gelling a flowable homogeneous composition containing cellulose acetate, an organic solvent, and water through a decrease in temperature; and hydrolyzing the cellulose acetate contained in the resulting gel.
