Abstract: Provided are a technique for preparing a porous cellulose medium without using a special gelling agent for a solution in which cellulose acetate serving as a raw material is dissolved; and a porous cellulose medium and the like produced using the technique. A method for producing a porous cellulose medium comprises the step of preparing a flowable homogeneous composition comprising cellulose acetate, a basic compound, and a solvent including water, and gelling the composition by deacetylation reaction of the cellulose acetate.
