Abstract: A method of producing an electrode-equipped plate spring of a railcar bogie includes: a resin removing step of partially irradiating a surface of fiber-reinforced resin, prepared by including electrically conductive fibers in resin, of a plate spring with a laser beam to partially remove the resin and partially expose the electrically conductive fibers; and an electrode forming step of attaching an electrode to an exposed region formed by partially exposing the electrically conductive fibers of the fiber-reinforced resin.

Abstract: The present invention has an object to provide a nonaqueous electrolyte secondary battery having high capacity and excellent cycle characteristics. A nonaqueous electrolyte secondary battery according to an embodiment of the present invention includes a positive electrode plate containing a lithium-cobalt composite oxide and a lithium-nickel-cobalt-manganese composite oxide (LiaNibCocMn1-b-cO, 0.9<a?1.2, 0<b?0.8, 0<c?0.9) having an average primary particle size of 1.2 ?m to 5.0 ?m and a negative electrode which contains one of silicon (Si) and silicon oxide (SiOx, 0.5?x<1.6) and which includes a negative electrode active material that stores and releases lithium ions.
