COLLECTOR AND ELECTRODE STRUCTURE, NON-AQUEOUS ELECTROLYTE CELL, ELECTRICAL DOUBLE LAYER CAPACITOR, LITHIUM ION CAPACITOR, OR ELECTRICITY STORAGE COMPONENT USING SAME

An object of the present invention is to improve an adhesion between the surface of a conductive resin layer and an active material, which are provided to a current collector. Another object of the present invention is to improve a high rate characteristics or electrode lifetime of a non-aqueous electrolyte battery, an electrical double layer capacitor, a lithium ion capacitor and the like which uses the current collector. A current collector prepared by forming a resin layer possessing conductivity on a conductive substrate, is provided. A surface roughness Ra of the resin layer possessing conductivity is 0.1 µm or higher and 1.0µm or lower. In addition, when a coating thickness of the resin layer possessing conductivity is taken as t [µm] and the average angle of inclination of the resin layer surface is taken as θa [degree], (1/3)t + 0.5 ≤ θa ≤ (1/3)t + 10 is met.
