This battery electrode is provided with: an electrode main body including a current collector and an active material layer provided on the current collector; and an electrode tab connected to the current collector and extending in the first direction. The electrode main body has: a convex first curved end portion positioned on the rear side of the electrode tab in a second direction intersecting the first direction; a first non-curved end part which is connected to the first curved end part and which forms a convex first corner part toward the rear side at a connection site with respect to the first curved end part; a convex second bent end portion located on the front side of the electrode tab in the second direction; and a second non-curved end portion which is connected to the second curved end portion and which forms a convex second corner portion toward the front side at a connection portion with respect to the second curved end portion. The curvature radius of the first bent end portion and the curvatur
