In a technology for manufacturing a battery electrode by applying an application liquid containing an active material, stripe-shaped pattern elements are formed at narrower intervals than before while contact between the pattern elements is avoided. An application liquid containing an active material is applied onto a base material 11, which will become a current collector, by a nozzle-scan coating method, thereby forming stripe-shaped active material pattern elements P1, P3, P5, . . . parallel to each other and extending in a Y-direction. After liquid components are volatilized from the application liquid and spread base parts of the pattern elements are shrunk, pattern elements P2, P4, P6, . . . are formed by applying the application liquid in stripes between the already formed pattern elements. In this way, it can be prevented that the base parts approach each other and the pattern elements touch each other when the adjacent patterns are simultaneously formed. |
