Abstract
(EN)
The secondary battery according to the present invention has a laminated body which is obtained by laminating a positive electrode, a separator, and a negative electrode in this order, wherein the weight per unit area of an adhesive material in a plane Z, which is a bonding plane X between the positive electrode and the separator and/or a bonding plane Y between the negative electrode and the separator, satisfies relational formula (1): A (g/m2) + 0.02 (g/m2) < B (g/m2) [in formula (1), A represents the weight per unit area of an inner region P in plane Z, B represents the weight per unit area of an outer region Q in plane Z, the inner region P has a center matching the center of plane Z, is of a shape that is similar to the shape of plane Z, and accounts for 80% of the area of plane Z, and the outer region Q corresponds to the total region other than the inner region P in plane Z].
