Inner sheets of a photo album, the photo album, and a photo album manufacturing method are provided to restrain irregular curved parts from being formed on the surfaces of the inner sheets as moisture is dried and to secure sufficient strength by coating the surface of a folding portion with a polymer film. Inner sheets(100) of a photo album are folded and overlapped along a middle folding line(105). Inner surfaces(110) overlapped with facing each other and outer surfaces(120) positioned on the opposite side of the inner surfaces are coated with polymer films(130,130a,130b), respectively. Roughness of the polymer film applied on the outer surface of the sheet is higher than roughness of the polymer film applied on the inner surface. The polymer film is thermoplastic resin. |
