An electrostatic chuck includes an anisotropic heat conductor which is disposed between an attraction substrate and a first heater member, and has an upper surface and a lower surface, and a coefficient of thermal conductivity which varies depending on directions. The anisotropic heat conductor is disposed so that the coefficient of thermal conductivity in a plane direction is larger than the coefficient of thermal conductivity in a thickness direction. Further, the electrostatic chuck includes metal layers which are joined to the anisotropic heat conductor so as to cover the upper surface and the lower surface of the anisotropic heat conductor, and an adhesive layer which is provided on a surface of each metal layer, and joins the metal layer to the attraction substrate or the heater member. Moreover, at least one of the metal layers is a fused metal layer formed by solidifying a melted metal.
