A metal V-belt for transmitting power, looped between a drive pulley 6 and a driven pulley 11, and comprising endless belt-form metal rings 31 and numerous metal elements supported along these metal rings, wherein the metal rings comprise a plurality of thin, endless belt-form metal ring sheets 33(1) to 33(n) superposed in the radial direction, and of these, the thickness of the innermost metal ring sheet 33(1) is set to be less than the thickness of the other metal ring sheets 33(2) to 33(n). Here, the thickness of the innermost metal ring sheet is set on the basis of the ratio of the coefficient of friction between the innermost metal ring sheet and the metal element members to the coefficient of friction between the other metal ring sheets.
