PROBLEM TO BE SOLVED: To obtain excellent fire resistance by arranging a fire resisting heat insulation material layer on at least one face of a structural member to integrate them, and filling the gap of the joint part of the fire resisting heat insulation material layers with fire resisting material. SOLUTION: On one face of an FRP layer 1 constituted of reinforced fiber base material made of carbon fiber, glass fiber, or the like, and matrix resin of phenol resin, a fire resisting heat insulation material layer 2 made of a rock wool molding plate and phenol resin foaming body is stuck into integral construction, Next the FRP layers 1 formed out of reinforced fiber base material and matrix resin are arranged on both sides of a core material layer 6 such as plastic foam into sandwich construction 8, a fire resisting heat insulation material layer 2 is arranged on the surface of one FRP layer 1 into an integral structure, and further the joint part 3 of the fire resisting heat insulation material layers 2 is filled with foaming fire resisting material 4. Consequently, although it is light weighted, this structure can be provided with fire resistance and heat insulation.
