A V-belt (B) includes a rubber composition forming a portion () to be V-shaped side faces (). Organic nanofibers () and organic short fibers () are included in the rubber composition, and oriented along a belt width. In the rubber composition, a ratio of a storage modulus in a grain direction to a storage modulus in cross-grain direction is 5 or greater.

V-belt and production method therefor

A friction transmission belt includes short fibers arranged so as to protrude from a surface of a pulley contact-side part made of a rubber composition. The short fibers consist of aramid short fibers and non-aramid synthetic short fibers having a standard moisture regain of equal to or less than 4%.
