PROBLEM TO BE SOLVED: To provide a highly heat-resistant reinforcement canvas used for a heat-resistant conveyor belt having a heat-resistant rubber layer manufactured by hot vulcanization with an organic peroxide used as a vulcanizing agent and the heat-resistant conveyor belt in which the reinforcement canvas is used. SOLUTION: This reinforcement canvas for the heat-resistant conveyor belt is formed of polyketone fibers or polyketone fibers and the other fibers. The heat-resistant conveyor belt has the reinforcement canvas. The polyketone fiber is remarkably excellent in heat resistance due to its molecular structure. The polyketone fiber is also excellent in adhesiveness to rubber. Consequently, the reinforcement canvas for the heat-resistant conveyor belt in which the heat-resistant rubber-mixed rubber layer with the organic peroxide used as the vulcanizing agent is used can develop excellent reinforcing effect due to its excellent adhesiveness to rubber without deteriorating during hot vulcanizing.
