To provide a technology to reduce wind noise.SOLUTION: An antenna device includes: a ground conductor plate (51); a first conductor plate (12) having a pentagonal shape in plan view; a second conductor plate (11); a linear conductor (21); a wireless terminal (1) for connecting a second capacitor (31) and the ground conductor plate; an inductor (41); and an overhead wire voltage detection terminal (2) for connecting a fourth end opposite to a third end of the inductor to the ground conductor plate. Two sides sandwiching a third side of the first conductor plate are perpendicular to the third side.SELECTED DRAWING: Figure 2 【課題】風切り音を抑えるための技術を提供する。【解決手段】アンテナ装置は、グランド導体板（５１）と、平面視で五角形である第１の導体板（１２）と、第２の導体板（１１）と、線状導体（２１）と、第２のキャパシタ（３１）とグランド導体板とを接続する無線端子（１）と、インダクタ（４１）と、インダクタの第３の端部とは反対側の端部である第４の端部と、グランド導体板とを接続する架線電圧検知端子（２）とを備える。第１の導体板の第３の辺を挟む二辺は、第３の辺と垂直である。【選択図】図２
