PROBLEM TO BE SOLVED: To provide a conveyer belt securing high productivity without damaging buckling resistance. SOLUTION: A warp 5 and a weft 6 in a fiber reinforcement layer 4 are respectively and substantially composed of untwisted multi-filament yarn to make a twisting process unnecessary and to improve the productivity. Elongation when load is 1/10 of regulated tensile strength of the conveyer belt 1 is set at 0.5% or more and 2.5% or less, and tension cutting elongation is set at 25% or more and 40% or less, which generates moderate elongation at the time of passing around a pulley. Even if crimp of the warp 5 becomes smaller because of non-twisting of the warp 5 and the weft 6, this moderate elongation mitigates buckling stress generated in the warp 5 to avoid reduction of the buckling resistance.
