A shoe press belt includes a polyurethane in which a reinforcement base member is embedded, the polyurethane being in one piece with the reinforcement base member. The polyurethane constituting at least an outer circumferential surface of the shoe press belt is a thermosetting polyurethane obtained by curing an urethane prepolymer using a curing agent. The urethane prepolymer includes a first urethane prepolymer (A) obtained by a reaction between an aromatic diisocyanate and a polyol component containing an aliphatic polycarbonatediol represented by a chemical formula (1). In the chemical formula (1), m is a combination of two or more of integers of not less than 2 and not more than 12, and n is not less than 3 and not more than 33.
