PROBLEM TO BE SOLVED: To provide a belt for papermaking machine having excellent physical properties such as crack resistance, abrasion resistance, hair crack resistance, etc. SOLUTION: In the belt for papermaking machine in which an outer peripheral surface is laminated to the felt side of a base body, the belt for papermaking machine comprises an intermediate layer having an outer peripheral surface in contact with the base body and the outermost layer positioned on the outer periphery of the intermediate layer. The intermediate layer is a polyurethane cured with dimethyl-thiotoluenediamine, the outermost layer is a cured polyurethane cured with a curing agent except dimethyl-thiotoluenediamine or a thermosetting resin selected from an epoxy resin and an unsaturated polyester resin. A drainage channel is cut on the outer peripheral surface and the bottom of the drainage channel is cut to a position deeper than the interface between the intermediate layer and the outermost layer.
