A drying apparatus and a manufacturing system for an electrode plate are described. The drying apparatus includes a housing and a drying device. The housing is provided with a drying chamber that is provided with a strip inlet and a strip outlet. The drying device includes a first drying module, a second drying module, and a conveying mechanism. The first drying module and the second drying module are configured to dry a material strip, and the conveying mechanism is configured to convey the material strip, such that the material strip sequentially passes through the first drying module, the second drying module, and the strip outlet from the strip inlet. The drying device is provided with a first drying module and a second drying module, and the drying temperature of the first drying module is higher than the drying temperature of the second drying module.
