1. A method for manufacturing a coated sheet to form a coated layer by a process including a process for coating a coating
liquid including a resin material and a solvent on a substrate, and a drying process for drying a coated liquid, wherein said
drying process comprises:
performing an initial drying process without using a drying wind and at ordinary temperature, and
performing a thermal drying process under a drying wind flow after the initial drying,
wherein, in the thermal drying process, drying is performed under drying wind flow having an average wind speed of 10 m/s
or less until a viscosity of the coated liquid in the thermal drying process reaches at least 50 mPa·s at drying temperatures.
