Abstract: An electrostatic chuck device is provided in which the occurrence of cracking in a ceramic layer, the cracking being caused by a difference in thermal expansion between a substrate and a sleeve due to heat generated during formation of the ceramic layer, is suppressed. The electrostatic chuck device includes a substrate, a laminated body that is laminated on the substrate and that includes at least an internal electrode, and a ceramic layer that is laminated on the upper surface of the laminated body in the thickness direction. The electrostatic chuck device is such that the substrate has a through-hole provided so as to pass through in the thickness direction, a sleeve formed from an insulating material is inserted into the through-hole, and the sleeve is joined to the through-hole via a joining means at an upper portion of the substrate in the thickness direction.
