Abstract: There is provided a laminated glass excellent in sound insulating property. A laminated glass includes: a pair of glass plates facing each other; and an intermediate film sandwiched between the pair of glass plates, including alternately laminated at least one skin layer and two or more core layers, wherein the skin layer has a glass transition point of 15° C. or higher, and each of the core layers has a glass transition point of less than 15° C., and a ratio of a mass of the intermediate film with respect to a total mass of the intermediate film and the pair of glass plates is 14 mass % or more.

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.
