A water-soluble film forming component (A) including a water-soluble plasticizing component (C) such as sugar alcohol and at least one type of water-soluble polysaccharide (B) selected from an oligosaccharide (B1) and a polysaccharide (B2) having a cyclic structure is used to melt-form a film by a method such as extrusion molding, and an edible film having a low moisture content is obtained. The resultant edible film dissolves rapidly and has excellent shelf life (or storage stability) and texture in the mouth despite including a water-soluble polysaccharide.將包含:由寡糖(B1)及具環狀結構之多醣類(B2)中選出的至少一種水溶性多醣類(B)、及糖醇等的水溶性塑化成分(C)的水溶性薄膜形成成分(A),藉由擠出成形等進行熔融製膜,而得到含水量較少的可食性薄膜。所得可食性薄膜,縱使含有水溶性多醣類,保存性(或保存穩定性)及在口腔內的感覺仍優良,且可迅速溶解。
