To achieve an antenna that can be easily mounted on an automobile.SOLUTION: A speaker grille 10 is arranged in front of a speaker 16, and a grounding conductor plate 18 is formed to surround an opening part of the speaker 16. An antenna element is fixed to an antenna element substrate 22, and a grounding position of the antenna element is connected to the grounding conductor plate 18. At least a portion of the grounding conductor plate 18 is positioned at an area sandwiched between the speaker grille 10 and the speaker 16. The grounding conductor plate 18 has a speaker hole 24 through which the opening part of the speaker 16 is visible. A buffer member 32, provided between a peripheral part of the speaker 16 and the speaker grille 10, surrounds the opening part of the speaker 16. An edge of an inner periphery of a belt-like section 36 in the grounding conductor plate 18 intrudes into a grounding conductor groove 34 provided on an outer peripheral surface of the buffer member 18. The speaker grille 10 has on a back side a rib 28 protruding toward the buffer member 32.SELECTED DRAWING: Figure 2

    【課題】本発明は、自動車に搭載することが容易なアンテナを実現することを目的とする。【解決手段】スピーカグリル10はスピーカ16の前方に配置され、接地導体板18はスピーカ16の開口部を囲む形状を有している。アンテナ素子基板22にはアンテナ素子が固定され、アンテナ素子の接地箇所は接地導体板18に接続されている。接地導体板18の少なくとも一部は、スピーカグリル10とスピーカ16との間に挟まれる領域に位置している。接地導体板18は、スピーカ16の開口部が見通されるスピーカ穴24を有している。緩衝部材32は、スピーカ16の周辺部とスピーカグリル10との間に設けられており、スピーカ16の開口部を囲んでいる。接地導体板18における帯状区間36の内周の縁は、緩衝部材18の外周側面に設けられた接地導体溝34に入り込んでいる。スピーカグリル10は、緩衝部材32に向けて突出するリブ28を背面に有している。【選択図】図2
