    摘要: An electrostatic chuck for attracting and holding a substrate by using an electrostatic force includes a plurality of protrusion portions to be brought into contact with the substrate. The protrusion portions are formed of a ceramic dielectric including grains each having a specified particle diameter, and contact surfaces of the protrusion portions with the substrate are formed to have a surface roughness depending on the particle diameter.
