PROBLEM TO BE SOLVED: To provide a conveyor belt, hardly stained, having flexibility to easily wrap around a pulley without slipping, hardly elongating in traveling, and having strength endurable against repetitive use. SOLUTION: This conveyor belt is formed as a two-layer structure by arranging a polypropylene-based resin layer on a surface of polypropylene cloth. Tensile strength in the traveling direction of the conveyor belt is set to 450 N or more, and tensile elongation in the traveling direction is set less than 25%, and the problem can thus be solved.
