PROBLEM TO BE SOLVED: To provide a laminated plate which is formed by bonding plates with mutually different thickness together, and breakage of an end of the plate with thin plate thickness is reduced.SOLUTION: A laminated plate includes a first plate and a second plate bonded to the first plate via an intermediate film. The laminated plate further includes a first main surface of the first plate and a fourth main surface of the second plate arranged on sides opposite to the intermediate film, respectively, and a second main surface of the first plate and a third main surface of the second plate being in contact with the intermediate film, respectively. Thickness of the first plate is thicker than that of the second plate. In at least a part of an outer periphery of the laminated plate, on a cross-sectional surface orthogonal to the outer periphery, the first plate has a first linear chamfered part which extends diagonally from an end of the second main surface to the second main surface, and the second plate is located on an inner surface side of an extended line of the first linear chamfered part.SELECTED DRAWING: Figure 1

    【課題】異なる厚みの板を貼り合わせた積層板であって、板厚の薄い板の端部が破損することを低減した積層板の提供。【解決手段】第1板と、前記第1板と中間膜を介して接合される第2板とを備える積層板であって、前記第1板の、前記中間膜とは反対側に配される第1主表面と、前記第1板の、前記中間膜に接する第2主表面と、前記第2板の、前記中間膜に接する第3主表面と、前記第2板の、前記中間膜とは反対側に配される第4主表面と、を備え、前記第1板の板厚は、前記第2板の板厚よりも厚く、前記積層板の外周縁の少なくとも一部において、前記外周縁に直交する断面で、前記第1板は前記第2主表面の端部から前記第2主表面に対し斜めに延びる第1直線状面取り部を有し、前記第1直線状面取り部の延長線よりも面内側に前記第2板が位置することを特徴とする積層板。【選択図】図1
