Summary:The present invention has its object to provide a hydrostatic gas bearing excellent in a vibration-damping characteristic. The hydrostatic gas bearing is provided with a gas ejecting equipments composed of a cylindrical fine hole having a diameter of not less than 0.04 mm and not more than 0.4 mm,wherein a helium gas is ejected through the cylindrical fine hole. The cylindrical hole has a diameter D and a length L, and in the case where a relationship of D 4 /L is not more than 2×10 −4 mm 3 is established, the hydrostatic gas bearing excellent in the vibration-damping characteristic is specifically realized.
