Abstract
A negative electrode active material slurry is applied to one surface of a strip-shaped negative electrode core so as to form multiple lines of the negative electrode active material slurry, the lines extending in an X direction and being spaced from each other in a Y direction. Subsequently, while keeping the negative electrode core aloft, first hot air is blown toward the negative electrode core from at least a lower side in a vertical direction, and then, while keeping the negative electrode core aloft, first cooling air having a lower temperature than the first hot air is blown toward the negative electrode core from at least the lower side in the vertical direction so as to decrease the temperature of the negative electrode core to 40° C. or lower.
