[0002] [SOLUTION] A drying device 10 for an electrode roll 20 includes: a drying oven 30 that accommodates an electrode roll in which an electrode base material 21 is wound around a winding core 22; an outer-side heater 40 that heats the electrode roll from the outer side; an axial-side heater 50 that heats the electrode roll from the winding core side; a pressure reducer 60 that lowers the internal pressure of the drying oven; a sensor 70 that detects the temperature of the outermost portion of the electrode roll; and a control unit 80 that controls the operation of the outer-side heater and the like on the basis of the temperature of the outermost portion of the electrode roll as detected by the sensor. The control unit operates the outer-side heater and the axial-side heater so as to heat the electrode roll from both the outer and winding core sides. If the temperature of the outermost portion of the electrode roll reaches a target temperature that is lower than that is allowed as the upper limit temperature at the outermost portion, the control unit stops the operation of the outer-side heater, operates the pressure reducer so as to reduce the pressure within the drying oven, and heats using the axial-side heater while reducing pressure using the pressure reducer.",
