The invention relates to a cone ring of a synchronizer and a manufacture method thereof. The cone ring of a synchronizer includes the basal body (1) of the cone ring and a friction material layer (3); wherein, the cone ring of a synchronizer also includes a metal plate layer (2); the metal plate layer (2) is jointed on the inner cone surface and/or the outer cone surface of the basal body (1) of the cone ring; the friction material layer (3) is a metal alloy. The cone ring of a synchronizer provided by the invention greatly reduces the manufacture cost; simultaneously the friction material layer can be jointed on the basal body of the cone ring through the metal plate layer by utilizing a simple manufacture technique, thereby manufacturing the cone ring of a synchronizer with low cost and good synchronous effect. Besides, the cone ring of a synchronizer has the advantages of good wear resistance and long service life.
