Abstract

In a secondary battery, a positive electrode current collecting portion (32) and a negative electrode current collecting portion (36) are bonded with a part of a positive electrode current collector exposed portion (52A) and a part of a negative electrode current collector exposed portion (56A) of a laminated electrode body (50), respectively. A bonding portion (Wp) between the positive electrode current collecting portion (32) and the positive electrode current collector exposed portion (52A), and a bonding portion (Wn) between the negative electrode current collecting portion (36) and the negative electrode current collector exposed portion (56A) are formed at positions at which, when the full length in a short side direction of each of the current collector exposed portions (52A, 56A) of the positive electrode (51) and the negative electrode (55) is set as L, a distance (P) from the end close to the lid (16) in the short side direction is less than L/2.
