Abstract
An electrode for a secondary battery includes a substrate and an active material layer. The active material layer is placed on a surface of the substrate. In a surface of the active material layer, one or more grooves are formed. The groove extends linearly in a direction perpendicular to a thickness direction of the active material layer. The groove has an open portion on a periphery of the active material layer. The open portion opens in the direction perpendicular to the thickness direction. The groove includes a first region and a second region. The second region is interposed between the open portion and the first region. In a cross section perpendicular to a direction in which the groove extends, the first region has a first cross-sectional area, and the second region has a second cross-sectional area. The second cross-sectional area is smaller than the first cross-sectional area.
