PROBLEM TO BE SOLVED: To provide a positive electrode active material for a lithium battery, a positive electrode active material for a lithium battery, and a lithium battery capable of realizing high discharge capacity, stable charge / discharge cycle characteristics, high filling property and high output. The method for producing a positive electrode active material for a lithium battery according to the present invention comprises Li x A y D z PO 4 (where A is one selected from Co, Ni, Mn, Fe, Cu, Cr, D Is selected from Mg, Ca, Fe, Ni, Co, Mn, Zn, Ge, Cu, Cr, Ti, Sr, Ba, Sc, Y, Al, Ga, In, Si, B, rare earth elements or 2 or more and different from A, 0 ≦ x <2, 0 <y <1.5, 0 ≦ z <1.5), and a solvent containing water as a main component contains Li component, P A component, A component, D component and inorganic fine particles are added to form a solution, and then this solution is heated under pressure to produce Li x A y D z PO 4 .
