Abstract: A conveyor belt comprises woven fabric having a mesh structure which imparts the belt with air permeability permitting suction of air therethrough. In one embodiment, the woven fabric is such that a portion made in plain weave in a low-density weave pattern of prescribed width in which at least one warp yarn and at least one weft yarn are woven together alternates with a portion made in satin weave in a high-density weave pattern of prescribed width in which five to twelve warp yarns and the same at least one warp yarn as in the low-density weave pattern are woven together. This alternation of low-density weave pattern(s) and high-density weave pattern(s) may create stripe(s) disposed in the conveying direction of the belt. Portion(s) made in satin weave may be disposed at one or both side end(s) of the belt.
