To provide a vehicle antenna capable of receiving radio waves in a predetermined frequency band with a desired gain in a glass plate construct that is attached to a frame-shaped resin plate and includes a conductive film.SOLUTION: A vehicle antenna 1 includes: a glass plate construct 20 including a first glass plate having a first main surface and a second main surface and a conductive film 54 disposed on the second main surface side; a frame-shaped resin plate 10 that overlaps a peripheral portion 21 of the glass plate construct 20 in a plan view of the first glass plate; and an antenna 40 having a power feeding unit 41, an element 42, and a grounding portion 43. The glass plate construct 20 has a conductive region 20A including the conductive film 54 in the plan view of the first glass plate, the ground portion 43 is electrically connected to the conductive film 54, and the power feeding unit 41 and the element 42 are arranged outside the conductive region 20A.SELECTED DRAWING: Figure 1 【課題】枠状の樹脂板に取り付けられ、導電膜を備えるガラス板構成体において、所定周波数帯における電波を所望の利得で受信できる車両用アンテナを提供する。【解決手段】車両用アンテナ１は、第１主面と第２主面とを有する第１ガラス板、及び、第２主面側に配置される導電膜５４を含むガラス板構成体２０と、第１ガラス板の平面視において、ガラス板構成体２０の周辺部２１と重なる枠状の樹脂板１０と、給電部４１、エレメント４２、及びアース部４３を有するアンテナ４０と、を備え、ガラス板構成体２０は、第１ガラス板の平面視において、導電膜５４を含む導電領域２０Ａを有し、アース部４３は、導電膜５４と電気的に接続され、給電部４１及びエレメント４２は、導電領域２０Ａ以外に配置される。【選択図】図１
