PROBLEM TO BE SOLVED: To provide a membrane containing agar and/or agarose and having a small dispersion of membrane thickness and a good surface smoothness, and its manufacturing method. SOLUTION: A mixture formed by adding sericin to a compound containing agar and/or agarose, and water as occasion demands is made into a sheet-like gel. Thereafter, while a load of 0.01-2 kgf/cm2 is applied to the sheet-like gel, the sheet-like gel is dried at 0-40 deg.C to obtain a membrane containing the agar and/or the agarose. A porous material and/or a water absorbing material are laminated on one side or both sides of the sheet-like gel comprising the mixture which contains the compound containing the agar and/or the agarose and the cericin. The laminate gel and material are dried at 0-40 deg.C while a load is being applied. Thereafter, by removing the porous material and/or the water absorbing material, the membrane containing the agar and/or the agarose can be more effectively manufactured.
