Abstract
In a friction transmission belt including a rubber layer forming a pulley contact surface, the rubber layer includes a rubber composition containing hydrophilic inorganic filler and a sliding-resistant material. The sliding-resistant material protrudes from the pulley contact surface, and is at least one of hydrophobic resin particles and hydrophobic resin fibers having an official regain of 0.4% or below, and in the rubber composition, a content of the hydrophilic inorganic filler with respect to 100 parts by mass of the rubber component is 35 parts by mass or more.
