Abstract

In a power storage cell, a first electrode (10) includes: a current-collector foil (11); and an electrode material (12) partially coating the current-collector foil (11). The current-collector foil (11) has a coated portion (11a) and an uncoated portion (11b). The coated portion (11a) is coated with the electrode material (12). The uncoated portion (11b) is not coated with the electrode material (12), and is exposed to one side (Z1) of an axial direction (Z) of the wound electrode assembly (1) and extends in a winding direction (X) of the wound electrode assembly (1). The uncoated portion (11b) has a plurality of bent portions (11bC) bent toward a radial direction (R) of the wound electrode assembly (1), and a folded portion (11bD) formed by folding a region of the uncoated portion (11b) between adjacent bent portions among the plurality of bent portions (11bC).
