The present invention relates to a metallic glass film for medical application, which is an amorphous thin film metallic glass (TFMG) formed for covering the surface of a substrate (for example, a medical cutting instrument), so as to increase the wear resistance and the sharpness of the substrate, decrease the surface roughness of the substrate, protect the edge of the substrate from curl and chipping crack. In the present invention, the TFMG is a zirconium-based thin film metallic glass constituted by Zr material, Cu material, Al material, and Ta material with the atom percent of 53 at %, 33 at %, 9 at %, 5 at %, respectively. Moreover, the TFMG can also be constituted by Cu material, Zr material, Al material, and Ti material, and the atom percent of the Cu material, the Zr material, the Al material, and the Ti material are 48 at %, 42 at %, 6 at %, 4 at %, respectively.
