PURPOSE: A method for forming a protective film on a metallic decorative construction panel is provided to prevent damage to a gold-deposited portion or the separation of a protective film from the metallic decorative construction panel, thereby ensuring semi-permanent life span. CONSTITUTION: A method for forming a protective film on a metallic decorative construction panel comprises the steps of: applying masking ink(2) to the rest part of a metal plate(1) except for a specific part, inserting the ink-coated metal plate into a protective film forming apparatus including coating solution, and applying different electric potential to the coating solution and the metal plate to electrodeposit resin on the ink-removed part by ionization, thereby forming a protective film.
