A substrate mounting table (94) is equipped with a mounting table (2), an electrostatic chuck (6), and a bevel covering (5). The electrostatic chuck (6) has a supporting surface (6e) which is in contact with the whole of the rear surface of a wafer (W). The annular bevel covering (5) has an outer diameter (DA) which is greater than that of the supporting surface (6e), and an inner diameter (DI) which is smaller than that of the wafer (W). The bevel covering (5) is disposed such that, when viewed from the direction orthogonal to the supporting surface (6e), the bevel covering (5) surrounds the periphery of the wafer (W) supported on the supporting surface (6e). |
