PROBLEM TO BE SOLVED: To provide a deformed state detecting device for a pipe conveyor belt, enabling to easily and accurately detect the twisted state and a degree of crush of a rounded portion of the pipe conveyor belt. SOLUTION: At one end on the reverse face of the pipe conveyor belt 10 and at a central portion in the cross direction of the belt, a lug position signal generating means 2 and a bottom portion signal generating means 3 are arranged, respectively, which are each formed of a rubber magnet. Between the signal generating means 2, 3, intermediate portion signal generating means 4A-4D are also arranged, which are each formed of a rubber magnet. On the pipe-like rounded outer periphery of the conveyor belt 10, a plurality of receiving means 510-521 are arrayed for receiving signals from the signal generating means 2, 3, 4A-4D. The deformed state of the pipe conveyor belt 10 is detected in accordance with the signals from the signal generating means 2, 3, 4A-4D received by the receiving means 510-521.
