Abstract
The present invention aims to shorten a drying time for time for drying a coiled electrode. To this end, a drying device for drying the coiled electrode wound on a winding core includes a heating unit for heating the coiled electrode from a winding core side. Since this enables heat to be transferred from a core part toward a surface of the coiled electrode, tiny spaces can be generated between layers of an electrode and moisture can be evaporated from these spaces. Thus, moisture of the core part side, which has been difficult to evaporate, can be reliably evaporated and a drying time for the coiled electrode can be shortened.
