    • PURPOSE: A method for forming plating layer and a method for manufacturing circuit board using the same are provided to prevent no-plating by removing an anti-corrosive material remaining in a primer resin. CONSTITUTION: In a method for forming plating layer and a method for manufacturing circuit board using the same, a metal film coated with a primer resin is provided in one side(S110). The primer resin layer is formed by using the illuminance of a metal film(S120). The metal film is laminated on the insulating layer so that the primer resin layer is attached to an insulating layer(S122). The metal film is removed through etching(S124). The primer resin layer is restored to remove the metal film of anti-corrosive material remaining the primer resin layer(S130). A circuit pattern is formed in the primer resin(S140).
