A vehicular window glass comprises: a glass plate; a dielectric ; and an electrothermal film disposed between the glass plate and the dielectric, the electrothermal film including an electrically conductive film and band-like electrodes having a lower resistance than the electrically conductive film, the band-like electrodes being located along at least two opposed sides at the outer edge of the electrically conductive film and connected to the electrically conductive film in a DC manner, the electrically conductive film being energizable via the band-like electrodes, and is provided with a pair of electrodes located across the dielectric and facing the electrothermal film, and an antenna including a slot at least a part of which is formed in the band-like electrodes in such a manner as to be sandwiched between the pair of electrodes as viewed in plan, one end of the slot providing an open end opened at the outer edge of the electrothermal film.
