Abstract: An antenna device is provided with a substrate; an antenna coil formed into a loop-shaped or spiral-shaped on the substrate; a first metallic layer overlapping with a first part of the antenna coil in a planar view; and a second metallic layer overlapping with a second part of the antenna coil different from the first part. The first and second metallic layers are disposed on both sides of a center of an inner diameter portion of the antenna coil in a planar view, respectively. A slit formed between the first and second metallic layers overlaps with the inner diameter portion of the antenna coil in a planar view. At least one of the first and second metallic layers is formed on the substrate together with the antenna coil.
