A manufacturing method of a positive electrode plate for a non-aqueous electrolyte secondary battery includes a coating and drying step of coating a positive electrode active material layer and a protective layer onto a positive electrode core so that the protective layer forms a raised part between a portion inside a side end of a core exposed part in a width direction and a width-direction center, and then drying the positive electrode active material layer and the protective layer; and a compressing step of compressing the protective layer and the positive electrode active material layer so as to press the raised part formed in the coating and drying step and the positive electrode active material layer.
