A sputtering apparatus for performing sputtering operation by using a rectangular target made of ferromagnetic material, the apparatus includes an electrode in which one first permanent magnet is disposed on each side edge of a front surface of the target, polarities of the first magnets confronting each other with the target interposed between the first magnets are opposite to each other, one second permanent magnet is disposed on each side edge of a rear surface of the target, polarities of the second magnets confronting each other with the target interposed between the second magnets are opposite to each other, and the polarity of each second magnet disposed on the rear surface of the target is the same as that of the first magnet disposed on the front surface of the target.
