摘要： PROBLEM TO BE SOLVED: To prevent uneven thickness at the end of an active material layer even if the active material layer is formed intermittently on a strip metal foil, in the manufacturing process of the electrode in an electrode assembly, and to eliminate some steps required for bonding a separator and the electrode, when enveloping the electrode with the separator.SOLUTION: The manufacturing method of an electrode includes a masking step, an active material layer coating step, and a peeling layer removing step. The masking step forms an adhesive layer 17 and a peeling layer 30 covering the adhesive layer 17 intermittently, and contiguously to a position on a strip metal foil 13 where an active material layer 14a is formed. The active material layer coating step coats the position where the active material layer 14a is formed and on the peeling layer 30 with a slurry S containing an active material. The peeling layer removing step removes the peeling layer 30 and exposes the adhesive layer 17 contiguously to the active material layer 14a.
