To provide a battery which can respond sufficiently to an instantaneous large current and a repetitive pulse-like large current.

A negative active material 3 of a negative electrode collector 1 and a positive active material 4 of a positive electrode collector 2 are caused to stand opposite to each other and a porous separator 5 having ion permeability is disposed between them. Meanwhile, a dielectric substance 6 is disposed on surfaces to which an active material is not applied of the negative electrode collector 1 and of the positive electrode collector 2. A battery element is formed by laminating the negative electrode collector 1, the separator 5, the positive electrode collector 2, and the dielectric substance 6 in this order and by coiling them. A nonaqueous electrolyte secondary battery is formed such that this battery element is inserted into a battery can 9, that a negative electrode lead 7 is welded onto the battery can 9, that an electrolytic solution is injected thereinto, thereafter that a positive electrode lead 8 is welded to a can lid 10, and that the battery can 9 is sealed with the can lid 10 with a gasket 11 interposed therebetween. A charge storing part is constituted of the negative electrode collector 1, the dielectric substance 6, and the positive electrode collector 2, while a nonaqueous electrolyte battery structure part is constituted of the negative electrode collector 1, the negative active material 3, the separator 5, the positive active material 4, and the positive electrode collector 2.
