In a secondary battery, a positive electrode current collecting portion and a negative electrode current collecting portion are bonded with a part of a positive electrode current collector exposed portion and a part of a negative electrode current collector exposed portion of a laminated electrode body, respectively. A bonding portion between the positive electrode current collecting portion and the positive electrode current collector exposed portion, and a bonding portion between the negative electrode current collecting portion and the negative electrode current collector exposed portion are formed at positions at which, when the full length in a short side direction of each of the current collector exposed portions of the positive electrode and the negative electrode is set as L, a distance from the end close to the lid in the short side direction is less than L/2.
