This antenna device is provided with: a feed coil (30) that is connected to a feed circuit; a first conductor surface (11) having a first slit (11S) that extends toward the outer edge direction; and a second conductor surface (12) having a second slit (12S) that extends toward the outer edge direction. The feed coil (30) is arranged in a position where the feed coil (30) overlaps the first slit (11S) when viewed in plan. The feed coil (30) and the first conductor surface (11) are magnetically coupled to each other. The first conductor surface (11) and the second conductor surface (12) are magnetically coupled to each other. The first slit (11S) and the second slit (12S) are arranged in positions where the slits partially overlap each other when viewed in plan. At least a part of the first slit (11S) overlaps a portion of the second conductor surface (12) other than the second slit (12S) when viewed in plan.
