Zusammenfassung:	A sample stage includes plural pushup pins that move a sample up/down above the stage, a recessed and protruding dielectric film on which the sample is loaded, a feeding port disposed on the film and through which gas is fed to a gap between the sample and the film, and openings of through-holes in which the pushup pins are housed, and the stage is connected to a feeding/evacuation conduit including a feeding-path that communicates with the port and through which gas fed to the gap flows, an evacuation-path that communicates with the opening and through which gas fed to the gap is discharged, and a connection-path through which the feeding-path and the evacuation-path communicate. With communication between the feeding-path and the evacuation-path via the connection-path interrupted, gas from the feeding-path is fed to the gap and into the through-hole via the gap.
