PROBLEM TO BE SOLVED: To provide a method for manufacturing a V-ribbed belt in which scraps are prevented from being generated by eliminating a grinding process for ribbed channels and the belts with various circumferential lengths can be molded by biaxial molding and a method for vulcanization without using a vulcanizer is inexpensively used. SOLUTION: A cylindrical rubber body 15 is set on a main shaft side mold 17 in which recessed parts 19 and projected parts 20 are alternately provided and a following shaft side mold 18 and a tension is provided thereon and a core wire 22 is spirally wound on the back face of the cylindrical rubber body 15 and a belt back face member 25 is wound thereon to manufacture a belt molded body 27. (2) Thereafter, the belt molded body 27 is heated and while the back face is pinched by a pair of pressing belts 34, it is embossed on the recessed parts 19 and the projected parts 20 to perform continuous vulcanization. (3) After vulcanization and a pair of the pressing belts 34 are moved in the direction separating from the belt molded body 27, a cooled belt sleeve 38 is taken out from the main shaft side mold 17 and the following shaft side mold 18 to finish it into the V-ribbed belt.
