PURPOSE:To prevent a coating agent from creeping into an opening section at the center of a component to be coated by the back side, by forming the central section of a support stand of a soft material of a given diameter and thickness and pressurizing the soft material to be deformed in the thickness direction of the component to be coated. CONSTITUTION:With a first valve 3 connected with a vacuummizing device, and a valve 4 connected with a pressure supplying device, a component 14 to be coated is placed on a chucking component 11. When a rotating device 2 is started, the first valve 3 is opened and the component 14 to be coated is adsorbed to a support stand 5 through a hole 13 of the chucking component 11 and rotates integrally. When the number of rotation comes up to a given number, the second valve 4 is opened, and a thin wall section 11a is expanded by the pressure applied and deformed along an opening 14a of the component 14 to be coated. By dropping a coating agent 15 to effect coating in said state, the coating agent 15 is prevented from creeping into the opening 14a by back side.
