Abstract: An electrostatic chuck includes a dielectric substrate, a base plate which is a metallic member joined to the dielectric substrate and in which a gas hole is formed, and a vent plug arranged inside the gas hole. The vent plug has a porous section which is a section made of a porous ceramic with air permeability, and a dense section which is a section made of a dense ceramic without air permeability, and which surrounds a whole circumference of the porous section from an outer circumference side. The porous section and the dense section are formed together into one piece by sintering without sandwiching a joining material made of a material other than a ceramic.
