A method for manufacturing a coated sheet that may form a coated layer having a uniform film thickness by a coating liquid even when a substrate has a large area. A method for manufacturing a coated sheet to form a coated layer by a process including a process (1) for coating a coating liquid including a resin material and a solvent on a substrate, and a drying process (2) for drying a coated liquid, wherein a value L obtained in drying process (2) satisfies a following relationship;.intg..times..sigma..function..times..function..eta..functio- n..times..times.d>.times..function. ##EQU00001## (where: T: total period of drying process [sec]; .sigma.: surface tension of coated liquid [mN/m]; h: thickness of coated liquid [m]; and .eta.: viscosity of coated liquid [mPasec]).
