To provide a new method for manufacturing an active material for a nonaqueous electrolyte secondary battery.
A method for manufacturing an active material for a nonaqueous electrolyte secondary battery, the active material containing a powder composed of oxide particles 3 of a lithium-containing complex oxide that contains lithium (Li) and one or more kinds of metallic elements other than lithium, includes the steps of: melting the surfaces of raw material particles 1 composed of a lithium-containing complex oxide that contains lithium and one or more kinds of metallic elements other than lithium and can absorb and desorb lithium reversibly, in a molten salt obtained by melting a molten salt material that contains lithium in a molar ratio higher than that of lithium contained in a raw material powder containing the raw material particles 1; and extracting a product from a mixture of the product and the molten salt obtained in the melting step.
