To allow a belt conveyor to be applicable to various kinds of loads by forming the belt conveyor so that a first belt and a second belt which is arranged inside or outside the first belt to convey a load placed on its surface, are lapped one over the other, and forming the second belt by material differed from that of the first belt.

This belt conveyor 1 is provided with a rotationally driven pulley 2A, and an endless belt 3 which is laid over the pulley to convey a load on its upper surface. In this case, a first belt 3a and a second belt 3b which is arranged inside or outside the first belt to convey the load placed on its surface, are structured to be lapped one over the other, and the second belt is formed of material differed from that of the first belt.
