Zusammenfassung:	According to one embodiment, an electrode structure (10) is provided. The electrode structure (10) includes an electrode (20) and a separator (22). The electrode (20) includes an active material-containing layer (20b). The separator (22) includes a layer (23) provided on a main surface (S1) of the active material-containing layer (20b). The layer (23) includes organic fibers (231) and a resin mass (232). The resin mass (232) is in contact with a portion of the main surface (S1) of the active material-containing layer (20b). The resin mass (232) is integrated with a portion of the organic fibers (231). When a length of the resin mass (232) is represented by a circumscribed quadrilateral of the resin mass (232), a length of a first side of the circumscribed quadrilateral and a length of a second side adjacent to the first side are each 10 µm or more.
