PURPOSE:To prevent deflection and vibration and precession of a ceramic long body from occurring, to prevent thereby decrease in yield of a raw material and ununiformness of the film thickness from occurring when a coating film is formed and to prevent the ceramic long body from being broken when the coating film is formed on the ceramic long body while it is rotated. CONSTITUTION:An apparatus for forming a coating film on a ceramic long body 1 while the ceramic long body 1 is rotated is provided. The ceramic long body 1 is held and rotated by means of a rotating apparatus 2. A material for coating film is fed on the rotating ceramic long body 1 by means of an apparatus 7 for feeding the material for coating film to form a coating film. Rotating bodies 5A and 5B follow the rotation of the ceramic long body 1 when it is rotated. |
