Provided is an electrode active material that is obtained by coating a surface of each particle of Li w A x DO 4 (provided that, A represents at least one selected from the group consisting of Mn and Co, D represents one or more selected from the group consisting of P, Si, and S, 0 < w ‰¤ 4, and 0 < x ‰¤ 1.5) with a coating layer containing Li y E z PO 4 (provided that, E represents at least one selected from the group consisting of Fe and Ni, 0 < y ‰¤ 2, and 0 < z ‰¤ 1.5) and a carbonaceous electron conductive material. The electrode active material of the invention may be obtained by drying slurry obtained by suspending particles of Li w A x DO 4 in an aqueous solution containing a Li source, an E source, a PO 4 source, and a carbon source, and by subjecting the resultant dried product to a heat treatment under a non-oxidizing atmosphere. |
