A producing method for a positive electrode plate includes a positive electrode paste preparing process of preparing a positive electrode paste including carbon nanotubes, positive active material particles, and a solvent, a coating process of coating the positive electrode paste on a surface of a current collector to form a positive electrode paste layer on the surface of the current collector, and a drying process of drying the positive electrode paste layer to form a positive electrode mixture layer. The carbon nanotubes have the characteristics of being attracted by magnets, and the carbon nanotubes included in the positive electrode paste layer are attracted toward a side of the current collector by the magnets at least any one of directly before the drying process or during the drying process.
