PROBLEM TO BE SOLVED: To provide a laminated structure having such a structure that two resin sheets are laminated, which enables a reinforcing material to be appropriately inserted into the laminated structure without lowering strength and rigidity.SOLUTION: A laminated structure includes: a first resin sheet formed on a front surface side; a second resin sheet that is formed on a rear side and faces the first resin sheet with a hollow portion therebetween; and a long-sized reinforcing material extending in a first direction in the hollow portion. The second resin sheet has: a first projection that projects from a sheet surface on the front surface side of the second resin sheet toward the first resin sheet and extends in a belt shape in a first direction along a side wall surface of the reinforcing material, when the laminated structure is viewed in plan view; and a second projection that projects from a sheet surface on the front surface side of the second resin sheet to a sheet surface on the rear side of the first resin sheet, extends in a belt shape when the laminated structure is viewed in plan view, and is connected to the first projection on the side wall surface on the side of the reinforcing material.SELECTED DRAWING: Figure 1 【課題】２枚の樹脂シートを積層させた構造を備えた積層構造体において、強度および剛性を低下させず、かつ補強材を適切に挿入できるようにすること。【解決手段】実施形態の積層構造体は、おもて側に形成された第１の樹脂シートと、裏側に形成され、中空部を隔てて第１の樹脂シートと対向する第２の樹脂シートと、中空部内において第１方向に延設された長尺状の補強材と、を備える。第２の樹脂シートは、第２の樹脂シートのおもて側シート面から第１の樹脂シートに向けて突出し、積層構造体を平面視で見た場合に、補強材の側壁面に沿って第１方向に帯状に延びる第１の突出部と、第２の樹脂シートのおもて側シート面から第１の樹脂シートの裏側シート面まで突出し、積層構造体を平面視で見た場合に帯状に延びており、補強材の側の側壁面において第１の突出部と連結している第２の突出部と、を有する。【選択図】図１
