To provide a belt for a pipe conveyor, capable of efficiently preventing parts near both side edge of a belt main body from being longitudinally torn, capable of maintaining the pipe shape even in curve traveling, capable of improving sealing properties on the overlapping part when the belt is rolled into a pipe shape, and capable of effectively preventing the belt from meandering in traveling.

In a belt main body 3, a plurality (shown in three layers) of core canvas 6 are buried between an upper rubber layer 4 and a lower rubber layer 5. The lateral rigidity of parts 3a near both side edges in the width direction of the belt main body 3 is set lower than the lateral rigidity of the central part 3b of the belt main body 3.
