An antenna device suppresses reflection of electromagnetic waves from a human body or other conductors, which causes the electromagnetic waves to be sufficiently emitted in a target direction. The antenna device includes an antenna pattern and a metasurface layer. The metasurface layer is a layer that is layered on the antenna pattern and disposed on the human body side. The metasurface layer includes a first low-loss film and a second low-loss film. A first metasurface is formed on the first low-loss film. A second metasurface is formed on the second low-loss firm.

The conductive sheet includes one or more transparent base sheets stacked into a layer, transparent conductive films, light-excluding conductive electrode films, and first resist layers, which are layered sequentially on the uppermost and lowermost surfaces thereof. The first resist layers are exposed simultaneously on both surfaces, and after development, the transparent and light-excluding conductive electrode films are simultaneously etched, the first resist layers are stripped away, then second resist layers are formed as coating on the both surfaces in an outer edge portion, so that the light-excluding conductive electrode films are etched only in the central window portions. Thus, circuit patterns of the transparent conductive films are exposed.
