摘要： In a secondary battery, a current collector plate (10) and an electrode group (4) are joined together with a joint portion (19) interposed therebetween. The current collector plate (10) includes a covered portion (13) and a housing (14). The covered portion (13) includes a melting portion (11) and a guide portion (12). The melting portion (11) is located closer to the outside of the electrode group (4) than the tip surface S of the exposed end when the exposed end is housed in the housing (14). The guide portion (12) is located closer to the center of the electrode group (4) than the tip surface S. In the joint portion (19), a plurality of exposed end portions (1a), (1a), . . . are located close to each other, and are joined to the current collector plate (10).
