PURPOSE:To carry out electrodeposition coating always at a fixed film thickness, by carrying out coating while varrying the effective working area of the electrode plate opposed to a material to be coated, according to electricity conduction time or transferring velocity thereof in electrodeposition cell. CONSTITUTION:When the material 1 to be coated such as car body is transferred by a hanger 2 and an overhead conveyer 3, and attained to a position B, a limit switch 8 is functioned and contactors 10a-10j are turned on through a control part 6a of a DC source apparatus 6. At the position B, passing time or transferring velocity of the material 1 are detected by a detecting means 23. The material 1 is further dipped in bath, and whole thereof is sunk therein. During this, both collector rings 5a, 5b are engaged with a bus bar 3, and electrodeposition is carried out between the cathode material 1 and the first anode plate 15 connected to the apparatus 6. Thereat, members of the contactors 10a-10j to be turned on are varied, based on a prescribed electricity conduction time or transferring velocity measured during transferring.
