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
