description The present invention relates to a positive electrode active substance for non-aqueous electrolyte secondary batteries which comprises particles comprising a polyanionic compound and carbon, and a lipophilic treatment agent with which the respective particles are coated, wherein the positive electrode active substance has an average particle diameter of 1 to 50 µm. The positive electrode active substance preferably has an oil absorption of not more than 20 mL/100 g. The positive electrode active substance according to the present invention exhibits a good compatibility with a resin and is excellent in packing property and dispersibility in the resin, and therefore can provide an electrode sheet in which the positive electrode active substance is filled with a high packing density.
