Abstract
A planar conductor including a cutout that penetrates in a thickness direction and extends from an outer edge portion toward an inner side, a coil antenna magnetically coupling with the planar conductor by a magnetic flux passing through the cutout, and a fit-in member filled into at least a portion of the cutout and including a metal oxide film provided on at least a side surface portion thereof which is in contact with the planar conductor, are included. Thus, an antenna device which does not impair appearance while maintaining strength by using a metal casing, and a communication apparatus including the antenna device, are provided.
