摘要：
An electrode capable of preventing variations in electrical performance to stabilize performance and improve yields is provided. An electrode structure includes: an electrode including an current collector and an active material layer arranged on the current collector; and an electrode lead arranged on the active material layer, wherein a hole is arranged so as to penetrate the electrode and the electrode lead, and the electrode and the electrode lead are folded back around the hole in a direction away from the hole so that the electrode is placed inside, and the thickness of the active material layer in a region where the electrode lead is not arranged is uniform, and the thickness of the active material layer in a region where the electrode lead is arranged is nonuniform.
