A kind of composite metal coil/plate includes one parent metal coil/plate and at least one clad metal coil/plate as well as an interlayer composed of atoms of a brazing filler, the parent metal and the clad metal. The interlayer is about 2-10 .mu.m in thickness. The present invention also relates to a method of manufacturing composite metal coil/plate. The method comprises pre-cladding the parent and clad metal coils/plates as well as the brazing filler foil in an inert or reductive atmosphere at 850-1000.degree. C., and hot rolling cladding the same under inert or reductive atmosphere at 900-1050.degree. C. A composite metal plate is obtained after cooling.
