PURPOSE: A producing method of a complex metal oxide-containing rubber additive, and an inorganic vulcanization accelerator using thereof are provided to remove the possibility of the generation of harmful nitrosoamine, and to improve the vulcanization accelerating property. CONSTITUTION: A producing method of a complex metal oxide-containing rubber additive comprises the following steps: forming an aqueous inorganic carrier dispersion(S110); forming a complex metal salt aqueous solution including more than two metal salt(S120); mixing the complex metal salt aqueous solution with the aqueous inorganic carrier dispersion(S130); and adjusting the pH into 9~10(S140); drying and calcining the mixture(S150). The surface of an aqueous inorganic carrier inside the aqueous inorganic carrier dispersion is coated with the complex metal salt oxide.
