In the present invention, the substrate 10 is made of a conductive metal material such as magnesium, a magnesium alloy, aluminum, an aluminum alloy, copper, a copper alloy, nickel, a nickel alloy, , Pressing or polishing (etching), coating, plating, and the like. However, it is desirable that the present invention is not limited to the materials and processing methods listed above.

6, the electrodeposited liquid 410 filled in the solution tank 400 and the electrodeposited liquid 400 electrically connected to the electrodeposited liquid 400 through the hanging part 140 of the bracket 100 made of a conductive metal material, The positive electrode (+) is supplied from the power supply unit 600 to the electrodeposition liquid 410 as a means for allowing a direct current to flow through the electrodeposited liquid 10 to deposit paint particles contained in the cationic electrodeposition liquid 410 on the surface 11, (-) power is supplied to the object (10) corresponding to the counter electrode to supply electric power to the object (10).

The components included in the bracket 100 of the present invention may be formed of a material such as SUS (Steel Special Use Stainless) or the like which does not chemically degrade the electrodeposited liquid 410 and does not easily wear due to electrodeposition coating, However, this is only one example.
