Provided is a positive electrode material containing lithium iron phosphate as a positive electrode active material, having a large charge and discharge capacity, high rate adaptability, and good charge and discharge cycle characteristics, a simple manufacturing method thereof, and a high performance secondary battery assembled therewith. A positive electrode active material represented by the general formula Li n FePO 4 (where n represents a number of 0 to 1) is included as a main component, and vanadium (V), chromium (Cr), copper (Cu), and zinc (Zn) And at least one heterometal element selected from the group consisting of indium (In) and tin (Sn). This anode material can manufacture the halide of the said metal element as a raw material. |
