PURPOSE:To apply powder paint to the entire surface of a metal material uniformly and continuously, in a painting apparatus using a fluidized immersion method, by providing a shield plate having a notch part and a shield part at a position spaced apart from the metal material in a fluidized tank. CONSTITUTION:Air in an air chamber 2 supplied by a blower (b) is allowed to pass through a porous body 3 and mixed with the synthetic resin powder (a) in a fluidized tank 4 having said powder received therein to form a fluidized bed. At this time, a shield plate 10 partially preventing the rising stream of the fluidized bed is provided so as to leave a predetermined distance from the under surface of the wire or rod-shaped metal material 5 passing through the fluidized tank 4 and, therefore, a strong part and weak part are alternately generated in the rising stream by the shield part 9 and notch part 10 of the shield plate 10 and, as a result, the generation of a pinhole due to the fusion deficiency on the under surface of the metal material 5 can be prevented.
