To provide steel plate member superimposed structure which can be improved in both of bending rigidity and torsional rigidity, and vehicle body structure.SOLUTION: The steel plate member superimposed structure comprises: a first steel plate 11 in which Young's modulus in a rolling direction and Young's modulus in a rolling orthogonal direction in the steel plate plane are higher than Young's modulus in a rolling 45° cross direction crossing the rolling direction at a cross angle of 45°, and a ratio of maximum and minimum Young's modulus is 1.1 or more; and a second steel plate 12 in which Young's modulus in a rolling 45°cross direction crossing a rolling direction at a cross angle of 45°is higher than Young's modulus in the rolling direction and Young's modulus in the rolling orthogonal direction in the plane of the steel plate, and a ratio of maximum and minimum Young's modulus is 1.1 or more, and which indicates in-plane anisotropy of Young's modulus. The first steel plate and the second steel plate are so combined as to face each other.SELECTED DRAWING: Figure 2

    【課題】曲げ剛性とねじり剛性をともに向上することが可能な鋼板部材重ね合わせ構造、車体構造を提供すること。【解決手段】鋼板部材重ね合わせ構造であって、鋼板の面内における圧延方向のヤング率及び圧延直交方向のヤング率が、前記面内において前記圧延方向と交差角度45°で交差する圧延45°交差方向のヤング率に比べて高くかつヤング率の最大値と最小値の比が1.1以上とされる第1の鋼板11と、鋼板の面内において圧延方向と交差角度45°で交差する圧延45°交差方向におけるヤング率が、前記圧延方向のヤング率及び圧延直交方向のヤング率に比べて高くかつヤング率の最大値と最小値の比が1.1以上とされたヤング率の面内異方性を示す第2の鋼板12とを備え、前記第1の鋼板と前記第2の鋼板が対向するように組合せられていることを特徴とする。【選択図】図2
