PROBLEM TO BE SOLVED: To provide an inexpensive conveyor belt easy to be deformed in a direction wherein both ends of the conveyor belt in the cross direction come close to each other and easy to be manufactured. SOLUTION: This conveyor belt for a pipe conveyor is moved for circulation, repeating a deformation thereof from a flat shape into a cylindrical shape due to coming close of both ends in the cross direction to each other and a reverse deformation. This conveyor belt comprises a plurality of non-rubber layers 5 arranged to be layered along the belt surface of the conveyor belt 1 inside the conveyor belt 1 formed from a rubber 2 as a main material, and this conveyor belt is deformed in a direction wherein both the ends 11 and 11 of the conveyor belt 1 in the cross direction thereof come close to each other by forming the non-rubber layer (shrinkage canvas 9) of the non-rubber layers 5 into a layer having contractive performance larger than that of other non-rubber layers (core canvas 8).
