    Abstract: A V-ribbed belt has a cord made of polyester-based fibers, the total fiber fineness of which is 2200 dtex or more and 5500 dtex or less. A fiber fineness of the cord per belt width corresponding to a single V-shaped rib ranges from 10000 dtex to 19000 dtex. A belt dry-heat shrinkage force per belt width corresponding to a single V-shaped rib is 44 N or more. The belt dry-heat shrinkage force is a load increase with respect to a belt length of 300 mm in 30 minutes after applying, in an atmosphere of 150° C., a load of 6N in the belt longitudinal direction and holding the belt.
