An electrode material, an electrode forming paste, an electrode plate, a lithium ion battery, and a method for manufacturing the electrode material that can realize stable charge / discharge cycle characteristics and high durability are provided. The electrode material of the present invention is Li x A y D z PO 4 (where A is one or more selected from the group of Co, Mn, Ni, Cu and Cr, D is Mg, One or more selected from the group of Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare earth elements, 0 <x ≦ 2, 0 <y ≦ 1, 0 ≦ z ≦ 1.5) This is a surface-coated Li x A y D z PO 4 particle in which Fe is present on the surface of the particle and the surface of the particle containing Fe is coated with a carbonaceous film. The Li x A y D z PO 4 particles have a Li elution amount of 200 ppm to 700 ppm and a P elution amount of 500 ppm to 2000 ppm when immersed in a sulfuric acid solution (pH = 4) for 24 hours.
