Abstract
A manufacturing method of metal and plastic composite bodies integrated by etching a surface of a metal member and forming a thermoplastic resin on an etching surface may include forming a printing layer which prints a pattern or a character on an exposed surface of a metal member and a protective layer for protecting the printed pattern thereon, grease-removing and cleaning to remove a passivation oxidized film at a rear side of the metal member to be integrally coupled with a plastic portion, surface-treating a surface by using and etching a ferric chloride solution in a range of pH 3 to 4.5 so as to form a minute unevenness at the rear side, removing a smut generated in the surface-treating process, and molding for integrally forming the plastic portion with the metal member.
