Abstract

This invention provides a rechargeable battery with a nonaqueous electrolyte, comprising a continuous sheet-like core and a mixture layer formed on the core. An electrode plate has an exposed part of the core provided along one side parallel to the longitudinal direction of the core. The mixture layer contains a material which can occlude and release a lithium ion. A porous film is provided on at least a part around the end face of the mixture layer in the exposed part of the core and the mixture layer. The thickness of the porous film in its part located at the end face of the mixture layer parallel to the exposed part of the core and located on the exposed part side of the core is larger than the thickness of the porous film in its part located at the center in the width direction of the mixture layer.
