    Abstract: A substrate stage and a plasma processing apparatus is provided to reduce replacement of an electrostatic chuck for a long period of time since the substrate stage has an oxide film made of a IIIA group element of a periodic system, which is highly resistant to plasma, and prevent reduction in cooling efficiency of a focus ring by forming a thin coating covering a focus ring placement part. A substrate stage for mounting a substrate(W) which is subjected to a plasma process, comprises a focus ring placement part(39), and a substrate mounting part(40). The focus ring placement part is configured to place a focus ring(19) that surrounds a substrate mounted on the substrate stage. The substrate mounting part overhangs beyond the focus ring placement part at an inside position of the focus ring placement part, having an electrostatic chuck(16) having a mounting drawing and holding the substrate on an upper side of the substrate mounting part, and an oxide film(38) of a predetermined thickness and made of a IIIA group element of a periodic system.
