Abstract
The present invention provides a current collector having a conductive layer which is excellent in adhesion strength and can exhibit a PTC function for stably contributing to safety, when used for an electrode structure for non-aqueous electrolyte batteries or for electrical storage devices. A current collector, including a metal foil and a conductive layer formed on at least one side of the metal foil, the conductive layer being formed partially or entirely on the surface of the metal foil; is provided. Here, the conductive layer contains core shell particles including core particles 114 having insulating crystalline polymer as a main component, and a shell layer 116 having conductivity, the shell layer 116 being formed on the surface of the core particles 114.
