To provide a vehicle window glass having an antenna capable of receiving both VHF band and UHF band radio waves with a relatively simple configuration.SOLUTION: A vehicle window glass 101 includes a glass plate 10 and an antenna 20A provided on the glass plate. The antenna includes a feeding portion 21, a first element 30 electrically connected to the feeding portion and extending to a first open end 35, a second element 40 electrically connected to the feeding portion 21 and extending to a second open end 45, and a third element 50 electrically connected to the feeding portion 21 and extending to a third open end 55. The first element 30 includes a first portion 31 extending in a first direction (+Y) and a second portion 32 extending in a second direction (-Y) opposite to the first direction (+Y) by folding back from the first portion 31. The antenna includes the first element 30, the second element 40, and the third element 50 arranged in this order in a third direction (+X) different from the first direction (+Y) and the second direction (-Y).SELECTED DRAWING: Figure 1 【課題】ＶＨＦ帯とＵＨＦ帯の両方の電波を比較的簡素な構成で受信可能なアンテナを備える車両用窓ガラスを提供する。【解決手段】車両用窓ガラス１０１は、ガラス板１０と、ガラス板に設けられたアンテナ２０Ａと、を備える。アンテナは、給電部２１と、給電部に電気的に接続され第１開放端３５まで延伸する第１エレメント３０と、給電部２１に電気的に接続され第２開放端４５まで延伸する第２エレメント４０と、給電部２１に電気的に接続され第３開放端５５まで延伸する第３エレメント５０と、を有する。第１エレメント３０は、第１方向（＋Ｙ）に延伸する第１部分３１と、第１部分３１から折り返して第１方向（＋Ｙ）とは反対側の第２方向（－Ｙ）に延伸する第２部分３２とを、含む。アンテナは、第１エレメント３０、第２エレメント４０及び第３エレメント５０が、この順に、第１方向（＋Ｙ）及び第２方向（－Ｙ）とは異なる第３方向（＋Ｘ）に並ぶ。【選択図】図１
