PROBLEM TO BE SOLVED: To provide a battery in which there is no wrinkles in the boundary of the mixture layer coated part and the mixture layer uncoated part of an electrode substrate, and to provide a manufacturing method therefor.SOLUTION: The manufacturing method of a battery includes an electrode mixture layer formation step (S1) for forming an electrode mixture layer 159 by coating a part of the surface of an electrode substrate 158 with an electrode mixture containing an active material and then drying, and a press step (S3) for pressing the electrode mixture layer 159 in the thickness direction. The manufacturing method of a battery further includes a framing step (S2) for framing a part of the surface of the electrode substrate 158 not coated with the electrode mixture layer 159 in the electrode mixture layer formation step (S1) or a mixture layer uncoated part 158b, prior to the press step (S3). |
