Provided are: an electrode for a non-aqueous electrolyte secondary battery, which is capable of obtaining high output characteristics; and a non-aqueous electrolyte secondary battery provided with the electrode. The electrode for a non-aqueous electrolyte secondary battery is provided with a current collector and a positive electrode active material layer that is arranged on the current collector and contains a positive electrode active material, and the positive electrode active material is configured from compound particles having a layered structure comprising two or more transition metals. The compound particles have an average particle diameter DSEM of 1 [mu] m or more and 7 [mu] m or less as observed by an electron microscope, and a ratio of 50% particle diameter D50 to the average particle diameter DSEM of 1 or more and 4 or less in a cumulative particle size distribution on a volume basis. The ratio of 90% particle diameter D90 in the cumulative particle size distribution on a volume basis to 10% part
