PROBLEM TO BE SOLVED: To provide a surface treatment film containing no chromium or lead superior in corrosion-preventive properties and lubricity, and to provide a solution for forming it and a metallic material coated with the surface treatment film. SOLUTION: The provided surface treatment film superior in corrosion-preventive properties and lubricity contains a filler with an aspect ratio of 30-17,000, metallic microparticles and a resin as main components, wherein the filler forms a multilayer. The provided solution for forming the surface treatment film with superior corrosion-preventive properties and lubricity, contains each main component dispersed in an organic solvent, and has a viscosity controlled to 10 pa S or lower at ordinary temperature and atmospheric pressure. The provided metallic material has the surface treatment film superior in corrosion-preventive properties and lubricity formed thereon. COPYRIGHT: (C)2004,JPO
