Zusammenfassung:	A secondary battery includes a laminate in which a positive electrode, a separator, and a negative electrode are stacked in stated order. Resistance A per unit area of a central region P that has a similar shape to a shape of a surface Z that is either or both of an affixing surface X of the positive electrode and the separator and an affixing surface Y of the negative electrode and the separator, that has a center at the same position as a center of the surface Z, and that has an area equivalent to 10% of area of the surface Z is larger than resistance B per unit area of a region Q other than the central region P at the surface Z.
