Lithium secondary battery positive electrode plate and lithium secondary battery

A nonaqueous lithium secondary battery comprises a positive electrode (31) which inserts/detaches lithium ions, and includes a collector on which a positive electrode active material for inserting/detaching lithium ions, a conduction assistant for increasing electric conduction of the positive electrode active material, and a binding agent for binding the positive electrode active material and the conduction assistant are applied, a negative electrode (32) for inserting/detaching lithium ions, and a separator (33) for separating the positive electrode and the negative electrode where a ratio (B/A) of an average particle diameter of the conduction assistant (A) to an average particle diameter of the positive electrode active material (B) is from 0.1 to 100, and the conduction assistant includes at least clustered amorphous carbon.
