Abstract
A vehicle windshield includes a window plate and an anti-fogging film provided on an interior side surface of the window plate, with a first region and a second region within a see-through region. The anti-fogging film is not on the first region but on the second region. The first region includes a belt-like region in an upper portion of the see-through region. The second region is a region that includes at least a test area B and that includes a continuous projection portion provided on an upper side. The anti-fogging film in the second region has a minimum film thickness of no less than 5 μm. At least a boundary between the first region and the second region excluding the projection portion has no perspective distortion and is formed by a boundary line having a linewidth of 10-200 μm that is visually recognized by scattering of incoming light.
