PROBLEM TO BE SOLVED: To simply produce a resin composite pipe having excellent strength against external pressure. SOLUTION: An inner layer forming process for continuously supplying a reinforcing material 21 and a resin material 22 to the surface of a mandrel 5 rotated while propelled in its axial direction to form an inner layer 2, an intermediate layer forming process for continuously supplying a connection material 31 and a resin mortar 32 connected each other continuously to the surface of the inner layer 2 in such a state that the inner layer 2 is uncured to form an intermediate layer 3, and an outer layer forming process for continuously supplying a resin material 41 and a reinforcing material 42 to the surface of the intermediate layer 3 in such a state that the intermediate layer 3 is uncured to form an outer layer 4 are provided and, in the intermediate layer forming process, the connection material 31 is embedded in all of the inner, intermediate and outer layers 2, 3, 4 to produce a resin composite pipe 1. |
