description PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery having excellent load characteristics, and an electrode that allows the formation of the lithium ion secondary battery.SOLUTION: The problem is solved by an electrode for a lithium ion secondary battery and the electrode as a positive electrode and/or a negative electrode. The electrode for the lithium ion secondary battery comprises: an electrode mixture layer containing oxide particles; active material particles capable of occluding and discharging Li; and a resin binder. The oxide particles have an average primary particle diameter of 1 to 20 nm. and have no peak in the range of 2 =20° to 2 =70°, or the half-width of the peak with the highest intensity is 1.0° or greater in the powder X-ray diffraction spectrum. The percentage of the oxide particles is in the range of 0.1 to 10 mass%, where the total mass of the active material particles and the oxide particles is made to 100 mass%.
