PROBLEM TO BE SOLVED: To provide a metallic amorphous magnetic film, which has a high permeability in a frequency band of several 100 MHz or higher and in particular, in a high-frequency zone band which is not smaller than 1 GHz as a high-frequency magnetic material, and which can be easily manufactured, and also to provide a magnetic element, inductor and transformer which use the magnetic film. SOLUTION: A high-frequency Co-based metallic amorphous magnetic film 4 contains Co as a main component and an amorphous phase containing one or more of elements Fe, Zr, Hf, Nb, Mo, Ta, W, V and Ti as a main phase. The real part of the complex permeability at 100 MHz is 300 or more and an imaginary part thereof is 20 or less, the rear part of a complex permeability at 1 GHz is 300 or more, and the imaginary part thereof is 200 or less.
