PROBLEM TO BE SOLVED: To provide a V-ribbed belt capable of eliminating generation of sound by inhibiting a minute slip in water pouring in using the V-ribbed belt as an automobile belt for an engine having a high variation in rotation. SOLUTION: A cotton short fiber and a para-aramid shot fiber are contained in a compressed rubber layer 6 and are projected from rib side surfaces 9. The projected para-aramid short fiber is fibrillated. In addition, a V-ribbed belt 1 contains the cotton short fiber 10-40 parts by weight, and the para-aramid short fiber 5-10 parts by weight to 100 parts by weight of the rubber of the compressed rubber layer in the contents of the cotton short fiber and the para- aramid short fiber.
