摘要： A plurality of first current collector parts (112a) are drawn out from a stacked part (100a). An exterior material (200) encloses a battery element (100). A first tab (310) is connected to the plurality of first current collector parts (112a). The plurality of first current collector parts (112a) between the stacked part (100a) and the first tab (310) have a first region (RG1). In the first region (RG1), a thickness of a bundle including the plurality of first current collector parts (112a) in a third direction (Z) decreases from the stacked part (100a) to the first tab (310), and a decrease rate of the thickness decreases from the stacked part (100a) to the first tab (310).
