PROBLEM TO BE SOLVED: To provide a method for outsert-molding a belt with protrusions capable of outsert molding the protrusions on a supporting protrusion part of the belt with a high mounting strength. SOLUTION: The method for outsert-molding the belt with protrusions comprises the steps of setting the belt 2 having the protrusion part 1 integrally protruded from a back surface in a mold, injecting a resin in the mold, and outsert molding protrusions 4 with this injection resin in a state in which a base is sandwiched between forked connecting parts 5 of a base at both surfaces in a longitudinal direction of the belt of the part 1, thereby integrally providing the protrusions 4 erected on the back surface of the belt 2. In order to mold in this manner, through holes 6 for passing in a belt longitudinal direction is provided at the mold, when the resin is injected in the mold to outsert mold the protrusions 4 at the part 1, the resin filled in the holes 6 is integrally connected with the part 5 to be molded so that the part 5 is molded to sandwich the belt of the part 1 between both the surfaces.
