The present invention provides a cathode active material for a secondary battery capable of effectively suppressing adsorption of moisture, which can obtain a high-performance lithium ion secondary battery or a sodium ion secondary battery, and a method for manufacturing the same. That is, the present invention relates to a formula (A): LiFe a Mn b M c PO 4 , formula (B): Li 2 Fe d Mn e N f SiO 4 , or formula (C): NaFe g containing at least iron or manganese It is a cathode active material for a secondary battery in which an oxide represented by Mn h Q i PO 4 is supported with a water-insoluble conductive carbon material and carbon formed by carbonization of a water-soluble carbon material. |
