Disclosed herein is a brazing method for joining using anamorphous sputtered coating layer as a filler, the methodcomprising forming an amorphous coating layer through asputter coating on a joining part between base metals (Step1); and heating the joining part of Step 1 (Step 2).When the multi-component amorphous inserting alloyaccording to the present invention is coated on the surface ofbase metals using a sputtering method that is one of aphysical vapor depositions, there are effects such that themulti-component target composition can be intactly maintainedon the coating layer of base metals; the uniformity ofinserting layer according to the positions, such as, theprecise thickness control and the uniform applying of basemetals surface can be secured; and also perfect interfacecontact can be performed to secure the uniformity andreproducibility of the joint part when joining.
