This electrode for an electricity storage device is provided with: a conductor plate having a first surface including at least one first recess and a second surface located on the opposite side from the first surface, the first surface having a first region located outside the first recess; and a first composite film having a first layer containing an insulating material, a first conductive layer, and a second conductive layer. The first layer is located between the first conductive layer and the second conductive layer. The first conductive layer of the first composite film is connected to the conductor plate in the first recess. The second conductive layer of the first composite film is connected to the first conductive layer at a position overlapping the first recess when viewed from the normal direction of the first region of the conductor plate. 蓄电器件用电极，其包括：导体板，其具有包括至少一个第1凹部的第1表面、和位于第1表面的相反侧的第2表面，第1表面具有位于第1凹部的外侧的第1区域；和第1复合膜，其具有含有绝缘材料的第1层、第1导电层和第2导电层。第1层位于第1导电层与第2导电层之间。第1复合膜的第1导电层在第1凹部与导体板连接。第1复合膜的第2导电层在从
