Abstract: The present invention relates to a vehicle windshield including a laminated glass in which a first glass plate, a first adhesive layer, an infrared reflective film, a second adhesive layer, and a second glass plate are laminated in this order, wherein a total thickness of the first glass plate and the second glass plate is 4.1 mm or less, the infrared reflective film contains a laminate in which 100 or more resin layers having different refractive indexes are laminated, the infrared reflective film has thermal contraction rates, wherein a thermal contraction rate in the direction which the thermal contraction rate being maximum is 1.5% or more and 2.0% or less, and a thermal contraction rate in the direction orthogonal to the aforementioned direction is 1.5% or more and 2.0% or less.

Abstract: Glass for a vehicle includes a glass plate; a test-region A demarcated in the glass plate, the test-region A being specified in JIS R3212; a shielding layer provided more outwardly than the test-region A in a plan view; an information transmission/reception region demarcated within an opening portion provided in the shielding layer, and through which a device mounted in the vehicle transmits/receives information; and an infrared reflective layer positioned peripheral to the information transmission/reception region in a plan view, the infrared reflective layer having a portion that overlaps with the shielding layer in a plan view, wherein a solar direct transmittance of the test-region A is 60% or less and a solar direct reflectance of a region in which the infrared reflective layer is provided peripheral to the information transmission/reception region is greater than a solar direct reflectance of the test-region A by at least 5%.

Abstract: A door glass for a vehicle includes a laminated glass having a first glass plate, a first adhesive layer, an infrared-reflective film, a second adhesive layer, and a second glass plate laminated in this order. The infrared-reflective film includes a laminate in which 100 or more layers of resin layers having different refractive indices are laminated, and has a thermal shrinkage rate of greater than 0.6% and less than 1.2% in a direction in which the thermal shrinkage rate becomes maximum, and in a direction perpendicular to the maximum direction. In an area where the laminated glass is visible when mounted on the vehicle, the outer periphery of the infrared-reflective film is positioned within a range of up to 10 mm inward from the outer periphery of the laminated glass in front view.
