Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode preventing drop of battery characteristics such as OCV failure caused because an active material extended from a current collector comes off and becomes foreign materials after electrode rolling in the manufacture of a lithium secondary battery. SOLUTION: The foreign materials are removed without leaving at an electrode plate end part by applying a brush 2 to the electrode plate end part in the horizontal direction and sucking immediately after rolling. The brush 2 is positioned on the inside of a suction port 1, suction is conducted at a flow velocity of 4-20 m3/min, thereby removing removed active materials without being dropped.
