PROBLEM TO BE SOLVED: To make an operation for inserting each block into a tension belt unnecessary in a fitting operation of the blocks into the tension belt, to facilitate insertion of the tension belt into a mold, and to remarkably shorten a time required for manufacturing the belt without generating a problem such as leakage of a resin. SOLUTION: In a method for manufacturing a high loading driving belt 1 in which the blocks 2 are fitted on the tension belt 3, the molds 30 and 31 having a tension belt holding part 32 and a cavity 33 for molding the blocks are used, and by injecting the resin into the cavity 33 in the molds under a condition where the tension belt 3 is set, the blocks 2 are molded and simultaneously, the blocks 2 are fitted to the tension belt 3. In the tension belt 3 and the tension belt holding part 32 of the mold into which the tension belt is inserted, the thickness of the tension belt 3 is 95-100% of the thickness dimension of the tension belt holding part 32, and the width of the tension belt 3 is set 102-120% of the width dimension of the tension belt holding part 32.
