A friction transmission belt having a rubber layer constituting a pulley contact surface, wherein the rubber layer is composed of a hydrophilic inorganic filler and a rubber composition containing a slip resistant material. The slip resistant material is at least one of hydrophobic resin particles and hydrophobic resin fibers that protrude from the pulley contact surface and have a process water content of 0.4% or less. The content of the hydrophilic inorganic filler in the rubber composition is 35 parts by mass or more based on 100 parts by mass of the rubber component. |
