To provide a structural material which is light-weight and can secure rigidity relative to force applied from one side of a flat plate.SOLUTION: A structural material 1 comprises a long side 3 and a long side 4 which are two long sides and two short sides 12 forming a rectangular frame body, a first branch 15 extending in a direction intersecting with the long side 3 and the long side 4 and two short sides 12 in the frame body to connect the long side 3 and the long side 4, and a second branch 11 extending in parallel with two short sides 12 in the frame body to connect the long side 3 and the long side 4. Two first branches 15 are provided so as to form an isosceles trapezoid with the long side 4 as a relatively long bottom side in the frame body, the second branch 11 divides the isosceles trapezoid equally and a hollow part situated outside the isosceles trapezoid among the hollow parts in the frame body is filled with a foam UF.SELECTED DRAWING: Figure 1

    【課題】より軽量で、平板の一方側から加わる力に対する剛性を確保可能な構造材を提供すること。【解決手段】構造材1は、矩形の枠体を形成する2つの長辺部である長辺部3及び長辺部4ならびに2つの短辺部12と、当該枠体内で長辺部3及び長辺部4ならびに2つの短辺部12と交差する方向に延出して長辺部3と長辺部4とを接続する第1支部15と、当該枠体内で2つの短辺部12と平行に延出して長辺部3と長辺部4とを接続する第2支部11と、を備え、第1支部15は、当該枠体内で長辺部4を相対的に長い底辺とする等脚台形を形成するよう2つ設けられ、第2支部11は、当該等脚台形を等分し、当該枠体内の空洞部のうち等脚台形の外側に位置する空洞部が発泡体UFで満たされている。【選択図】図1
