Abstract

An electrode (100) is manufactured by forming an active material layer (20) on a surface of an electrode current collector (10), forming a groove portion (21) on a surface of the active material layer (20), and peeling off a part of the active material layer (20). An electrode current collector (10) includes a metal foil (11) and an adhesive layer (12). The metal foil (11) includes a first region (11a) and a second region (11b). The adhesive layer (12) covers the first region (11a). In the second region (11b), the metal foil (11) is exposed. The active material layer (20) includes a first portion (20a) that covers the adhesive layer (12) and a second portion (20b) that covers the second region (11b). The groove portion (21) is formed in each of the first portion (20a) and the second portion (20b). The second portion (20b) is peeled off.
