Intended is to provide a collector for a nonaqueous secondary battery, which can retain the intensity of the collector when an electrode plate is manufactured and which can carry an active substance efficiently on the projections of the collector, the electrode plate for the nonaqueous secondary battery using the collector, and the nonaqueous secondary battery itself. The nonaqueous secondary battery collector is made of a metal foil for carrying at least an anode activating substance or a cathode activating substance thereon. The projections are formed in a predetermined array pattern on at least one face and have at least their crests uncompressed. The array pattern is formed of a row direction, in which the projections are arrayed straight at an equal pitch, and a column direction, in which the row units of the projections of one group arrayed in the row direction are arrayed at a predetermined interval in parallel with each other. Provided is the nonaqueous secondary battery collector, in which the projections of one group composing the row unit are different in the positions of the row direction from the projections of another row direction adjoining in the column direction. Further provided are the nonaqueous secondary battery electrode plate and nonaqueous secondary battery using the collector.
