A focus ring and a plasma processing apparatus are provided to obtain the same uniform plasma processing of an edge as a center of wafer and to reduce a deposition in the back surface of edge. A focus ring includes a lower member and an upper member. The lower member(9) is formed with a dielectric. An upper member(10) made of a conductive material is formed on the top of the lower member. An inclined portion that an outer circumferential side thereof is higher than an inner circumferential side is formed on the top surface of the upper member. The position of end of the outer circumferential side in the inclined portion is higher than the position of a surface of the wafer(W) to be processed. The inner circumferential side of the upper member is spaced apart from a circumferential edge of the wafer by a predetermined distance.
