摘要

The present invention improves the adhesion of an active material or the like to the surface of a conductive resin layer provided to a collector, and improves the high-rate characteristics or electrode life of a non-aqueous electrolyte cell, electrical double layer capacitor, lithium ion capacitor, or the like that uses the collector. Provided is the collector, wherein a conductive resin layer is formed to at least one surface of a conductive substrate. Also, the surface roughness (Ra) of the conductive resin layer is 0.1-1.0 µm inclusive. Furthermore, when the thickness of the conductive resin layer is t (µm) and the average angle of inclination of the roughness at the resin layer surface is ?a (degrees), the range (1/3)t + 0.5 = ?a = (1/3)t + 10 is satisfied.
