Abstract: The present invention relates to a chemically strengthened glass having a first principal surface and a second principal surface facing the first principal surface, at least a portion of the first principal surface being chemically strengthened, wherein the depth of a compressive stress layer in at least a portion of the first principal surface continuously changes. This chemically strengthened glass can be suitably used in an application in which chemical strengthening characteristics that differ among different regions in the same plane are desired in a chemically strengthened glass.

Abstract: A laminated plate includes first and second plates bonded to each other via an intermediate layer. The laminated plate includes a first main surface of the first plate opposite to the intermediate layer; a second main surface of the first plate and a third main surface being in contact with the intermediate layer; a fourth main surface of the second plate opposite to the intermediate layer. A thickness of the first plate is thicker than a thickness of the second plate. In a planar view, the laminated plate includes a peripheral region and an in-plane region. In a cross section orthogonal to an outer periphery of the laminated plate, a distance from an outermost periphery of the second plate to the first plate in a thickness direction with respect to the outermost periphery is three times or less a distance between the first and second plates in the in-plane region.

Abstract: The present invention relates to a laminated plate (laminated glass plate 102 for a vehicle) including a first plate (first glass plate 201) being curved in a first curved shape, a second plate (second glass plate 202) having a second shape that is different from the first curved shape, and an intermediate film 301 bonding the first plate and the second plate, in which the laminated plate has, in a planar view thereof, a peripheral region 313 and an in-plane region 314, and the peripheral region 313 has a flat region 313a and an undulating region 313b.
