    Abstract: PURPOSE: A plasma processing apparatus, a focus ring and a susceptor are provided to improve remarkably cooling efficiency of the focus ring without the increase of costs by providing a dielectric part and a conductive part for the focus ring. CONSTITUTION: A plasma processing apparatus includes a susceptor. The susceptor includes an electrostatic chuck(25) and a focus ring(30) connected with the electrostatic chuck through a contact portion. The focus ring is composed of a dielectric part(30a) with the contact portion and a conductive part(30b) on the dielectric part.
