Abstract
A vehicle window glass () includes a first glass sheet (), a second glass sheet () and an interlayer film () sandwiched between a second surface (S) of the first glass sheet and a third surface (S) of the second glass sheet. For weight reduction, at least one of the glass sheets () has a thickness of 2.0 mm or smaller. The interlayer film () has a main part () provided with a rigid layer and a peripheral part () formed of a non-rigid layer. The peripheral part () is disposed along an upper side of the vehicle window glass () which is exposed to air. Contact of water with the rigid layer of the main part () is prevented by the non-rigid layer of the peripheral part (). The rigid layer has a water content controlled to 0.5% or lower as measured by near-infrared spectroscopy.
