PROBLEM TO BE SOLVED: To provide a method for producing a silk sponge in which a silk sponge having a fine porous structure can be produced from a silk fibroin solution with a simple operation and at a low cost. SOLUTION: The silk fibroin solution is frozen, and the frozen state is maintained to apply mechanical stress to the silk fibroin dispersed and dissolved in the solution. The frozen state is further maintained until the crystallization is completed to insolubilize the silk fibroin to produce the silk sponge having a fine porous structure.
