A fiber-reinforced layer 3 having a woven structure in which warp yarns 4 extend in the longitudinal direction of the belt and weft yarns 5 extend in the width direction of the belt is embedded in a conveyor belt 1 as a core body 2, and the ratio A1/A2 of an exposed area A1 of the warp yarns 4 to an exposed area A2 of the weft yarns 5 is set to 3.0-5.0, in a plan view of the fiber-reinforced layer 3. In endless processing, a cover rubber 6 is separated, at the end sections 1a in the longitudinal direction of the belt, toward the width direction of the belt, a rubber component R is left as appropriate on a surface of the fiber-reinforced layer 3, and the left rubber component R is vulcanized by including therein a vulcanization adhesive 7 or the like, whereby the end sections 1a in the longitudinal direction of the belt are bonded together.
