Abstract
An electrode sheet drying apparatus includes a plurality of hot air blowers each having a nozzle. The nozzle has a first hot air guide having a first guide surface, a second hot air guide having a second guide surface. The nozzle is configured to blow band hot air toward an obliquely upstream side. An angle formed between the first guide surface and an undried active material layer is set to an angle at which the band hot air travels toward an upstream side along the undried active material layer over a distance longer than or equal to 15 times as large as a gap from a first upstream-side edge to the undried active material layer even without a spread prevention part.
