Abstract:
1. A laminated glass for a vehicle window, which comprises a first glass plate, a second glass plate having an infrared reflection film having a sheet resistance of at least 1 kΩ/□, and an interlayer having infrared shielding fine particles dispersed therein, interposed between the first glass plate and the second glass plate, the first glass plate being disposed on the car interior side, wherein the infrared reflection film comprises a stacked coating film (X) and a thin film (Y), the stacked coating film (X) has a coating film ( coating film ( the thin film (Y) has a multilayer structure made of an inorganic material on the non-glass plate side of the stacked coating film (X), the thin film (Y) and the coating film of the stacked coating film (X) are in contact with each other; and the thin film (Y) is a multilayer film having a high refractive index layer (c) made of a high refractive index inorganic material having a refractive index of at least 1.90 and having a geometrical thickness of from 5 to 40 nm and a low refractive index layer (d) made of a low refractive index inorganic material having a refractive index of at most 1.56 and having a geometrical thickness of from 5 to 40 nm alternately stacked in a totally even number of layers, and the layer in contact with the coating film (
