An antenna device includes a metal layer for forming an antenna element in a predetermined planar shape and a ground arranged on a lower side of the metal layer. The metal layer forms a first metal forming the planar shape, a notch portion formed at the first metal, and cutting out a part of an edge of the planar shape, a second metal being an electromagnetic field coupling element arranged with a predetermined distance spaced from the first metal inside the notch portion, and a feeder line formed outside the planar shape, and to be connected with the second metal via an opening portion of the notch portion. For the second metal, a width at the opening portion is smaller than a maximum width at a portion more inside the notch portion than the opening portion.
