Zusammenfassung:PROBLEM TO BE SOLVED: To provide a dc magnetron type reactive sputtering apparatus which allows preventing insulation breakdown induced by a semiconductor or dielectric compound thin film being deposited on a non-sputtering region and stably forming a high-quality sputtering film, in the DC magnetron type reactive sputtering apparatus using reactive gas to form an electrically conductive target and a semiconductor or an insulator.SOLUTION: In a DC magnetron type reactive sputtering apparatus, a deposition preventive plate 7 is provided to cover an upper part of a non-sputtering region 2 of an electrically conductive target 3. The electrical resistance between the target and the deposition preventive plate is 10 or more. A gap is provided between the deposition preventive plate and the target.
