[PROBLEMS] To provide a positive electrode active material layer coating composition capable of stably producing a positive electrode plate for a non-aqueous electrolyte secondary battery that does not easily cause tailing during coating, has excellent battery safety, and has a sufficient battery capacity. Offer things. In addition, the present invention provides a positive electrode plate for a non-aqueous electrolyte secondary battery that does not easily cause tailing, has excellent battery safety, and has a sufficient battery capacity. Furthermore, the present invention provides a high-capacity and high-quality non-aqueous electrolyte secondary battery that is assembled using the electrode plate and is excellent in safety. The positive electrode active material contains 100 parts by weight, the conductive material contains 0.5 to 2.5 parts by weight, and the binder contains 1.7 to 3.7 parts by weight. It is a coating composition for positive electrode active material layers characterized by containing 50% by weight or more of polyvinylidene fluoride having a weight average molecular weight of 300,000 to 400,000 based on the total amount of binder. The positive electrode active material layer coating composition is provided on one or both sides of a current collector, and a positive electrode plate for a non-aqueous electrolyte secondary battery, and Next battery.
