PROBLEM TO BE SOLVED: To provide an antenna device that supports a plurality of frequencies, suppresses a performance degradation due to the approach of a human body, and is hard to be affected by the noise generated by components on a substrate.SOLUTION: The antenna device includes: a feed part; a first element connected to the feed part; a second element connected to the feed part; a first fold part connected to an end point of the first element; a second fold part connected to a second fold part connection point that is a predetermined position of the second element; a foldback element connected so as to couple end points of the first fold part and the second fold part; and a second resonance circuit disposed at a second resonance circuit connection point that is a predetermined position of the second element between an open end and the second fold part connection point. |
