摘要： It is an object to provide an antenna unit capable of operating in response to a plurality of types of counterpart equipment that operate at different resonance frequencies while enhancing its passing characteristic, as well as providing a portable wireless device equipped with the antenna unit. An antenna unit that performs wireless communication originating from induction coupling includes a loop antenna coiled by a conductor in a planar shape; and a metallic plate that is positioned while displaced from the loop antenna in one direction and that partially encloses a circumference of the loop antenna when viewed from the direction, wherein each of ends of the metallic plate overlaps a portion of the loop antenna when viewed from the direction.
