The invention discloses a target with a metal glass coating. The ZraKbMcNd metal glass coating is formed on a substrate by sputtering, wherein K, M and N are selected from elements in VB group, VIB group, VIIIA group, IB group, IIIA group and IVA group; the atomic radius percentage of any two of K, M and N is not less than 15 percent; and a, b, c and d represent atomic composition percentage, wherein a is more than or equal to 30 percent and less than or equal to 77 percent, b is more than or equal to 11 percent and less than or equal to 50 percent, c is more than or equal to 4 percent and less than or equal to 15 percent, and d is more than or equal to 4 percent and less than or equal to 10 percent. The target is provided with a plurality of fan-shaped coating material units which are spliced into a disc or arranged continuously in a rectangular shape, wherein each coating material unit is provided with four element strips which consist of four metal elements, namely zirconium, K, M and N, and the number ratio of zirconium, K, M and N of all the element strips and the metal glass coating are in a sputtering generation proportional relationship.
