Zusammenfassung:	ProblemAn antenna device, suppressing reflection of electromagnetic waves from a human body or other conductors causes the electromagnetic waves to be sufficiently emitted in a target direction.Solution meansAntenna device (3), which is configured to be used in contact with or close to a human body or a conductor, includes an antenna pattern (17) and a metasurface layer (13). The metasurface layer (13) is a layer that is layered on the antenna pattern (17) and disposed on a human body side. The metasurface layer (13) includes a first low-loss film (20A), a second low-loss film (20B), a first metasurface (21A) formed on the first low-loss film (20A), and a second metasurface (21B) formed on the second low-loss film (20B).
