[Problem] To provide an electrode material for a lithium-ion rechargeable battery capable of improving the high-rate characteristics without deteriorating the capacity retention. In addition, and to provide an electrode including the electrode material for a lithium-ion rechargeable battery, a lithium-ion rechargeable battery including the electrode as a cathode, and a method for manufacturing the electrode material for a lithium-ion rechargeable battery. Means for Solving the Problem An electrode material for a lithium-ion rechargeable battery in which surfaces of inorganic particles represented by LiFexMn1-x-yMyPO4 (0.05≦x≦1.0, 0≦y≦0.14, here, M represents at least one element selected from Mg, Ca, Co, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, and rare earth elements) are coated with a carbonaceous film, and a standard deviation (n=5) of a G/D ratio obtained from a Raman spectrum spectroscopic measurement is 0.01 or more and 0.05 or less.
