PROBLEM TO BE SOLVED: To improve cracking efficiency of a conductive material by preventing the conductive material from being deposited to a housing inner wall surface of a stirring device.SOLUTION: An electrode manufacturing method includes the steps of: forming wet granulated particles by stirring at least an electrode active material, the conductive material and a solvent; and depositing an electrode material layer on a collector by rolling the wet granulated particles. In the electrode manufacturing method, the step of forming the wet granulated particles includes the step of cracking the conductive material by the stirring device. Stirring blades that are provided on a bottom of a housing 60 of the stirring device include: a shear blade 30 that shears a stirring object; and an upflow blade 40 that is provided on a lower stage than the shear blade 30 and generates an upflow in the stirring object. The upflow blade 40 is provided while being tilted from a horizontal line in such a manner that a front side in a direction of rotation is turned upwards, and a distal end portion is bent forwards in the direction of rotation.SELECTED DRAWING: Figure 2 |
