Abstract: An infrared heater is disposed on one side of an electrode sheet transferred along a transfer path. A radiation temperature sensor is disposed on the other side of the electrode sheet to measure the temperature of the back surface of the electrode sheet corresponding to the back side of a front surface portion of the electrode sheet that is the closest to the infrared heater. The radiation temperature sensor is configured such that the peak wavelength of infrared light radiated to the surface of the electrode sheet by the infrared heater is not included in the detectable wavelength range of infrared light detected by the radiation temperature sensor.
