摘要： PROBLEM TO BE SOLVED: To provide a postcurable resin pipe which has no problem of the flow of an uncured resin during storage and transportation and is excellent in handling and moldability. SOLUTION: In a postcurable resin pipe in which a wall part comprises an inner layer film 1, a postcurable intermediate layer 2, and an outer layer film 3, the intermediate layer 2 is formed by impregnating a reinforcing material with a liquid resin and increasing the viscosity of the resin. Since the viscosity of the liquid resin in the reinforcing material was increased to decrease its fluidity, there is no problem of the flow of the uncured resin during storage and transportation.
