PROBLEM TO BE SOLVED: To provide a method for producing a conveyer belt where, even in the case general-purpose polyester fiber is used for the warps of reinforcing layers, when foreign matter is bitten between a belt and a pulley, damage hardly occurs, and the elongation of the belt upon its use can be suppressed, and to provide the conveyer belt. SOLUTION: The warps 3 of reinforcing layers 2a, 2b composed of synthetic fiber fabric are composed of polyester fiber in which a cutting elongation is≤18%, a cutting strength is≥7.5 cN/dtex, and shrinkage stress produced upon heating from ordinary temperature to 200°C is≥0.08 cN/dtex, and, in the final heat treatment zone in a stage of performing adhesion liquid treatment, a tension of 0.05 cN/dtex to 0.07 cN/dtex is applied in the direction of the warps to the reinforcing layers 2a, 2b (synthetic fiber fabric). Next, an upper cover rubber layer 5 and a lower cover rubber layer 6 are stacked on the upper and lower parts of the reinforcing layers 2a, 2b, respectively, and vulcanizing is performed.
