An electrode plate production device includes a drying device and a plurality of surface state detection devices. The drying device is configured to dry a coating film for forming an active material layer that is coated on a surface of a substrate sheet for forming a current collector while the substrate sheet travels in a traveling direction. The coating film includes at least an active material, a bonding agent and a solvent. The surface state detection devices are configured to detect a surface state of the coating film in a noncontact manner. The surface state detection devices are arranged within the drying device in the traveling direction of the substrate sheet with respect to each other. |
