A secondary battery includes an electrode body that includes a positive-electrode sheet and a negative-electrode sheet, a prismatic exterior body that accommodates the electrode body, a metallic sealing plate that seals an opening of the prismatic exterior body, and a positive-electrode current collector that is electrically connected to the positive-electrode sheet and the sealing plate. The positive-electrode current collector includes a base that faces the sealing plate and a lead that is disposed on an end portion of the base. A projection is formed on the sealing plate. The projection is fitted in a connection opening that is formed in the base. The projection and the base are welded to each other.
A secondary battery comprising:
A method for manufacturing a secondary battery including an electrode body that includes a first electrode sheet and a second electrode sheet having a polarity different from a polarity of the first electrode sheet, an exterior body that has an opening and that accommodates the electrode body, a sealing plate that seals the opening, and a current collector that is electrically connected to the first electrode sheet, the current collector including a base that faces the sealing plate, the method comprising:
