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