PROBLEM TO BE SOLVED: To provide an antenna device with reduced deterioration in characteristics caused by surrounding metal bodies, and that is low in cost and size, and to provide a method of manufacturing the same.SOLUTION: An antenna device comprises: a dielectric substrate 21; a ground conductor 101 formed on a surface or an inner layer of the dielectric substrate 21; and at least one antenna conductor 1 formed on the surface or the inner layer of the dielectric substrate 21, and that includes an element of an inverted L-shaped antenna connected with an outer periphery of the ground conductor 101. The dielectric substrate 21 comprises at least one deletion part 31 where the dielectric substrate 21 is penetrated and removed, at least at a part of a region sandwiched between the ground conductor 101 and the antenna conductor 1.SELECTED DRAWING: Figure 1 【課題】本発明は、周囲の金属体による特性劣化の小さい、低コストかつ小型のアンテナ装置およびその製造方法の提供を目的とする。【解決手段】本発明に係るアンテナ装置は、誘電体基板２１と、誘電体基板２１の表面上または内層に形成されたグランド導体１０１と、誘電体基板２１の表面上または内層に形成され、グランド導体１０１の外周に接続された逆Ｌ型アンテナの要素を含む少なくとも１つのアンテナ導体１と、を備え、誘電体基板２１は、グランド導体１０１とアンテナ導体１とで挟まれた領域の少なくとも一部に、誘電体基板２１が貫通して削除された少なくとも１つの削除部３１を備える。【選択図】図１
