Abstract:
Provided is a laminated glass capable of suppressing multiple images and enhancing the heat shielding properties, and enhancing the uniformity of heat shield properties or color tone between one end side and the other end side of the laminated glass. A laminated glass according to the present invention has one end, and the other end being at the opposite side of the one end and having a thickness larger than a thickness of the one end; the laminated glass includes a first lamination glass member, a second lamination glass member, and an interlayer film arranged between the first lamination glass member and the second lamination glass member; the first lamination glass member has a wedge angle of 0.10 mrad or more; the wedge angle of the first lamination glass member is equal to a wedge angle of the interlayer film or larger than the wedge angle of the interlayer film, and the interlayer film contains a heat shielding substance.
