To provide a vehicle window glass capable of ensuring antenna gain.SOLUTION: A vehicle window glass includes a first glass plate having a main surface, a conductor layer which is arranged on the main surface side of the first glass plate and surrounded by an outer edge including three or more sides in plan view of the first glass plate, and an antenna that is arranged outside the outer edge in the plan view and receives radio waves in a predetermined frequency band. The antenna includes a power feeding section disposed apart from the conductive layer, and a linear antenna element electrically connected to the power feeding section. When the vehicle window glass is attached to a vehicle, the outer edge includes a first side substantially parallel to a metal edge formed on a metal portion of the vehicle, and the antenna element includes a first element extending from a first end to a second end in a non-conductive region sandwiched between the metal edge and the first side in plan view.SELECTED DRAWING: Figure 1 【課題】アンテナ利得の確保が可能な車両用窓ガラスの提供。【解決手段】車両用窓ガラスであって、主面を有する第１ガラス板と、前記第１ガラス板の前記主面の側に配置され、前記第１ガラス板の平面視において、３本以上の辺を含む外縁で囲まれた導電層と、前記平面視において前記外縁よりも外側に配置され、所定の周波数帯の電波を受信するアンテナと、を備え、前記アンテナは、前記導電層から離れて配置された給電部と、前記給電部に電気的に接続された線状のアンテナエレメントと、を有し、前記車両用窓ガラスを車両に取り付けたとき、前記外縁は、前記車両の金属部に形成された金属縁に略平行な第１辺を含み、前記アンテナエレメントは、前記平面視において、前記金属縁と前記第１辺との間に挟まれた非導電領域に第１端から第２端まで延伸する第１エレメントを含む、車両用窓ガラス。【選択図】図１
