PROBLEM TO BE SOLVED: To provide high quality coating capable of coping with a need for pursuit of high designability such as the overlapping of random colors by saving the equipment space in the case of multicolor spattering coating and decreasing the maintenance time of coating equipments such as the cleaning of the coating equipments. SOLUTION: Coating materials are supplied to a bell cup through feed tubes 7, 8 corresponding to the number of colors and the atomized particles free from the mixing of the coating materials each having the different color are formed by keeping the flow of the coating materials in the bell cup at laminar flow and atomizing so that the coating materials each having the different color are not mixed with each other at the time of atomizing. The multicolor sputtering coating is performed only with one piece of a rotary atomizing coating machine by using the rotary atomizing coating machine.
