Abstract
A drying method for drying a roll electrode for a negative electrode, comprising a first heating step of raising temperature of an electrode to a first temperature, a maintenance step of keeping a state of the electrode for a predetermined period of time after the first heating step, and a second heating step of raising temperature of the electrode up to a second temperature higher than the first temperature after the predetermined period of time has elapsed, wherein the first temperature is set to evaporation temperature of the moisture contained in the electrode or higher, and the second temperature is set to decomposition temperature of an additive contained in the electrode or higher.
