Zusammenfassung:	PURPOSE: A prestressed composite beam is provided to improve workability by not requiring a process for arranging internal reinforcing bars and to enable the easy arrangement of tendons. CONSTITUTION: A prestressed composite beam comprises an external steel material(110), internal plain concrete(120), steel frames(130), and a tendon(140). The top of the external steel material is open. The internal plain concrete is placed in the external steel material and has a hollow portion(S). The steel frames are fixed to the inner surface of the external steel material to be buried in the internal plain concrete. The tendon is placed across the steel frames in a longitudinal direction.
