PROBLEM TO BE SOLVED: To provide a heat sink of a plasma display apparatus which is simple in a manufacturing process and cheap in a manufacturing cost in manufacturing the heat sink through extrusion processing and rolling processing. SOLUTION: The heat sink manufacturing method of the plasma display apparatus and the manufacturing device by the same are formed with an air channel in widthwise direction and an air channel in lengthwise direction through an extrusion and a rolling processing to facilitate the processing with the continuous extrusion and rolling processing. Accordingly, the productivity is notably improved. COPYRIGHT: (C)2008,JPO&INPIT
