PROBLEM TO BE SOLVED: To form a hollow structure having various cross sections without using a complicated core and a complicated mold. SOLUTION: Three hollow lengthy CFRP elements 24, 26, and 28 are combined and bonded to one another to form a hollow structure 10. The cross-sectional shape viewed in the longitudinal direction of each CFRP 24, 26, or 28 is triangular. The CFRP element 24 and the CFRP element 26 are bonded together by a sharing side, and the CFRP element 26 and the CFRP element 28 are bonded together by a sharing side.
