An annular metal cord and an endless metal belt are provided which have superior breaking strength and which are easy to be produced. The annular metal cord includes an annular core portion 3 and an outer layer portion 4. The annular core portion 3 is formed by connecting together both ends of a first strand material 1 which is made up of six twisted first metal filaments 5. The outer layer portion 4 is formed by winding spirally a second strand material 2 which is made up of six twisted second metal filaments 6 around the annular core portion 3. The second strand material 2 is wound at a predetermined winding angle relative to a center axis of the annular core portion 3, and a winding initiating end portion and a winding terminating end portion thereof are connected together. Since it is not that six second strand materials 2 are not wound but that the second strand material 2 is wound six rounds, there only has to be the single second strand material 2, and there is only one connecting portion. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
