PURPOSE:To improve resistance to corrosion, erosion, weather and environment by providing a laminated protective layer combined with a titanium protective layer and resin protective layer. CONSTITUTION:An amorphous magnetic layer 3 having the axis of easy magnetization in at least the direction perpendicular to the film plane is formed via an interference layer 2 on a substrate 1. The titanium protective layer 4 consisting of a material selected from any of a titanium metal, titanium metal alloy or titanium compd. before attaining a stoichiometric compsn. and the resin protective layer 5 are successively formed on the magnetic layer 3. The resistance to corrosion and erosion is greatly improved by providing the laminated protective layer consisting of the above-mentioned combination, by which the resistance to weather and environment is improved.
