Abstract
PURPOSE:To increase the life characteristics, by providing a protective layer having an SiO2 vapor-deposited layer in contact on a magnetic metallic thin film. CONSTITUTION:On a base 1 made of high polymer such as polyester, polyimide or polyamide, nonmagnetic substance layers 2, 3 and magnetic metallic thin films 4, 5 are provided, and a high polymer protective layer 7 made of epoxy resin or the like is provided on the film 5 via an SiO2 vapor-deposited layer 6 of <=1,000Angstrom thickness, preferably.
