Abstract
Current collector, an electrode structure, a non-aqueous electrolyte battery, and an electrical storage device having superior shut down function are provided. According to the present invention, a current collector having a resin layer on at least one side of a conductive substrate is provided. Here, thermoplastic resin particles substantially free of a conductive agent are dispersed in a thermosetting resin base material containing the conductive agent to structure the resin layer; a value of mass ratio given by (thermoplastic resin particles)/(conductive agent) is 0.3 to 1.5; and a value given by (average thickness of conductive agent)/(average thickness of thermoplastic resin particles) is 0.3 to 4.0.
