The antenna coil includes a first antenna coil(34a) and a second antenna coil(34b). The first and the second antenna coils have different electromagnetic characteristics. The dielectric plate is used for supplying the electromagnetic field of the antenna coil to the inside of a vacuum chamber. The dielectric plate has a predetermined dielectric constant.
