PROBLEM TO BE SOLVED: To provide a manufacturing method of a combined segment constituted by integrating an internal reinforced concrete structure and an outer shell from an aspect of strength. SOLUTION: Rod-shaped steel materials 4 are installed on a steel shell equipped with main beams 1, joint plates 5, a skin plate 3 and longitudinal ribs 2 having opening parts 7 so as to cross longitudinal ribs 2 and the steel shell is filled with padding concrete 6 to form a combined segment. In this combined segment, the longitudinal ribs 2 are incorporated in and welded to the skin plate 3 on which the main beams 1 are temporarily placed at predetermined attaching positions, the rod-shaped steel materials 4 are subsequently inserted in the longitudinal ribs 2 to form a member composed of the skin plate 3, the longitudinal ribs 2 and the rod-shaped steel materials 4, this member is integrally molded along with the outer shell composed of the main beams 1 and the joint plates 5, the skin plate 3 and the longitudinal ribs 2 by welding and concrete 6 is cast in the formed outer shell.
