In a plasma oxidation treatment apparatus 100, dual plate structure 60 is arranged above a susceptor 2. An upper plate 61 and a lower plate 62 are made of a dielectric material such as quartz, separately arranged in parallel at a prescribed interval, for instance an interval of 5 mm, and have a plurality of through holes 61a, 62a. The two plates are arranged one over another by shifting the positions so that the through hole 62a of the lower plate 62 and the through hole 61a of the upper plate 61 are not overlapped.
