PROBLEM TO BE SOLVED: To provide a film containing agar and/or agarose which has an almost uniform film thickness and good surface smoothness, and a method for preparation thereof. SOLUTION: A mixture of a compound containing agar and/or agarose and, as necessary, water is processed into a sheet-like gel, and the sheet-like gel is dried at 0-40 deg.C while a load of 0.01-2 kgf/cm2 is applied to the sheet-like gel to obtain a film containing agar and/or agarose. A porous material and/or a water-absorbing material are laminated to one or both surfaces of the sheet- like gel containing agar and/or agarose, and the sheet-like gel is dried at 0-40 deg.C while a load is applied to the sheet-like gel to obtain a film containing agar and/or agarose more efficiently.
