A manufacturing method of iron oxide nano particle is provided to manufacture easily iron oxide nano particle at a low temperature by simple reaction, to be applied practically and to heighten effectiveness of the manufacturing process. A manufacturing method of iron oxide nano particle comprises steps of: reacting di-valent iron salt and tri-valent iron salt and into solvent of the chemical formula CnH2n+1 OH and forming an iron oxide nano particle precursor; and forming the iron oxide system nano particle by reacting a precursor with a base. The di-valent iron salt is one or more materials selected from a group consisting of iron(II) acetate, iron(II) nitrate and iron(II) halide. The tri-valent iron salt is one or more materials selected from a group consisting of iron(III) acetate, iron(III) nitrate and iron(III) halide.
