To improve shock absorbability and inter-layer adhesiveness and stably realize a satisfactory strength even in a case where a metal plate includes a recess and metal plates are bolted with each other regarding a multilayer panel comprising the metal plates and a shock absorption member which is held between the metal plates.SOLUTION: A multilayer panel comprises at least two metal plates and a shock absorption member which is held between the metal plates. The metal plate includes a plurality of through holes for bolts. One metal plate includes a plurality of recesses for bolting which are recessed to the side of the other metal plate. The through hole for bolts is provided in the recess for bolting. The recess for bolting of the one metal plate is in contact with the other metal plate without interposing the shock absorption member therebetween, and is laminated and fixed by bolting. In a projection observation of the multilayer panel from an upper side, the shock absorption member is not present within a range WD which is twice the diameter D of the through hole.SELECTED DRAWING: Figure 1

    【課題】金属板と該金属板に挟まれた衝撃吸収部材とを備えた積層パネルについて、金属板が凹部を有し、金属板同士がボルト締結されるような場合であっても、衝撃吸収性及び層間密着性に優れ、安定的に優れた強度を実現できることを目的とする。【解決手段】本発明は、少なくとも2枚の金属板と、該金属板に挟まれた衝撃吸収部材と、を備えた積層パネルであって、前記金属板は、複数のボルト用貫通孔を有し、一方の金属板は、他方の金属板側へ凹んだ複数のボルト締結用凹部を有し、該ボルト用締結凹部内に前記ボルト用貫通孔が設けられており、前記一方の金属板の前記ボルト締結用凹部が、前記衝撃吸収部材を介することなく、前記他方の金属板と接触し、ボルト締結により積層固定されており、前記積層パネルを上から投影観察した際、前記貫通孔の径Dの2倍の範囲内WDに前記衝撃吸収部材が存在しないことを特徴とする。【選択図】図1
