PROBLEM TO BE SOLVED: To provide a coating method of electrode paste for a battery capable of applying the electrode paste to a current collector, with less generation of stripe defects and with smooth surface. SOLUTION: In the coating method of a roll coater type using two rolls of a backup roll 10 and a measuring roll 20, and a reverse roll coater type using three rolls of the backup roll 10, an application roll 30, and the measuring roll 20, the measuring roll 20 is formed in a column shape, rotated in the same direction as the backup roll 10 or the application roll 30, and electrode paste 2 is applied to a current collector 1. |
