A drying method and a device each employ a specific range of infrared radiation which has a high transmissivity relative to a coated layer formed on a metal substrate and a high absorptivity relative to the substrate. The energy transmitted through the coated layer is absorbed in the substrate and changed into heating energy to heat the substrate surface. The backsurface of the coated layer is also heated and solidified. The surface of the coated layer is solidified at the termination of the drying process so that surface is not injured by evaporation of solvent from the coated layer. A combination of infrared radiation and a blow of hot air ensures that the coated layer will not experience irregular heating which helps to prevent the generation of pin holes in the coated layer and shortens the drying period. The blowing direction is oriented in the same or at right angles to the infrared radiation.
