A secondary battery according to an embodiment comprises a package container, and an electrode structure and electrolyte which are housed in the package container. The electrode structure (24) includes a positive electrode (18), a negative electrode (20), and a separator disposed between the positive electrode (18) and the negative electrode (20). The separator includes an organic fiber layer (23) deposited at least either on the positive electrode or the negative electrode. The organic fiber layer (23) has contact points where the organic fibers intersect with each other and form of these intersections are changed by tensile stress. |
