1. A laminated glass, comprising a first laminated glass member, a second laminated glass member and an interlayer film arranged between the first laminated glass member and the second laminated glass member; and
the first laminated glass member and the second laminated glass member each being a heat ray-absorbing plate glass other than a UV green glass,
provided that the infrared ray transmittance in the wavelength of 780 to 2100 nm of the first laminated glass member is defined as Ty1 and the infrared ray transmittance in the wavelength of 780 to 2100 nm of the second laminated glass member is defined as Ty2, the relationship between Ty1 and Ty2 being Ty1=Ty2, Ty1 and Ty2 each being in a range of 50% to 88%,
the interlayer film including an infrared ray reflection layer which reflects infrared rays, a first resin layer which is arranged on a first surface side of the infrared ray reflection layer and contains a thermoplastic resin, and a second resin layer which is arranged on a second surface side opposite to the first surface of the infrared ray reflection layer and contains a thermoplastic resin,
the first laminated glass member being arranged on the outside of the first resin layer in the interlayer film, and
the second laminated glass member being arranged on the outside of the second resin layer in the interlayer film, and
the infrared ray transmittance in the wavelength of 780 to 2100 nm of the first resin layer being higher by 10% or more than the infrared ray transmittance in the wavelength of 780 to 2100 nm of the second resin layer.
