A V-ribbed belt has a plurality of V-rib portions extending along a longitudinal direction of the belt and in parallel with one another. The V-ribbed belt includes a compression rubber layer including a frictional power transmission face at least a part of which is configured to come in contact with a V-rib groove portion of pulleys. The frictional power transmission face of the compression rubber layer is formed from a vulcanizate of a rubber composition containing a rubber component and a noise suppression improver. A V-rib angle of the V-rib portions is larger than a V-rib groove angle of the pulleys by 5° to 9°.
