摘要

An antenna unit is provided in a wireless communication apparatus which performs wireless communication. The antenna unit has a radio wave resonance part through which a radio wave is transmitted or received, an antenna ground part electrically connected to the radio wave resonance part, and a connection part which fixes the antenna ground part at such a position that the antenna ground part is closer to the radio wave resonance part than other ground parts of the wireless communication apparatus.
