Abstract:
1. A wireless communication device comprising: a wireless IC device configured to process a high-frequency signal; a radiation conductor coupled to the wireless IC device; a ground conductor connected to the radiation conductor; and a metal plate including first and second main surfaces arranged such that the ground conductor is coupled to the first main surface and a portion that defines a radiation element; wherein the metal plate includes a current path portion arranged to conduct a high-frequency signal current on a first main surface side to a second main surface side of the metal plate when a high-frequency signal is supplied from the wireless IC device through the radiation conductor and the ground conductor; and a conductive member electrically conducting the first main surface and the second main surface of the metal plate to each other is provided in the metal plate; and the current path portion is located in a surface boundary portion between the conductive member and the metal plate.
