PROBLEM TO BE SOLVED: To provide a coating booth ensuring coating quality and reducing the running cost of the coating process. SOLUTION: A wall body 5 is formed in a dome shape; a nearly hemispherical coating space 6 is formed within the wall body 5; and two or more air-jetting outlets 12 are arranged on the surface 2a of the inside wall 5a of the wall body 5 in an arch form with nearly equal distances from the target surface 2a of an article 2 to be coated. Thus, in the coating space 6, a uniform air flow traveling in the direction nearly perpendicular to the target surface 2a toward the target surface 2a of the article 2, and a coating material discharged from individual bell coating guns 3 is guided in the direction nearly perpendicular to the target surface 2a toward the target surface 2a of the article 2 by the air flow formed in the coating space 6, resulting in the improved efficiency of deposition of the coating material and improved coating quality. The running cost is reduced owing to the use of a blower with relatively low output. COPYRIGHT: (C)2006,JPO&NCIPI
