Beschreibung
Zusammenfassung:	A Johnsen-Rahbek force type electrostatic chuck including: a metal substrate; an electrode for electrostatic attraction provided on the metal substrate with an insulating layer interposed between the metal substrate and the electrode for electrostatic attraction; and a dielectric layer constituting an electrostatic attraction surface in contact with a workpiece. The dielectric layer includes a ceramic spray coating and a sealing component with which pores of the ceramic spray coating are filled, and the sealing component contains a metal organic salt containing a rare earth element.
