Abstract
A method of manufacturing a positive electrode includes: preparing a current collector foil having a first main surface and a second main surface; obtaining a granulated body in which a solvent remains by mixing a positive electrode active material, a conductive material, a binder, and the solvent with each other to obtain a mixture and granulating the mixture; obtaining a first positive electrode mixture layer by pressing the granulated body into a sheet shape; arranging the first positive electrode mixture layer on the first main surface; and heating the current collector foil in a state where the first positive electrode mixture layer is arranged on the first main surface, such that a temperature of the current collector foil becomes a softening point of the current collector foil or higher and that a temperature of the first positive electrode mixture layer is lower than a melting point of the binder.
