An object of the invention is to provide a portable wireless device that can attain a high level of antenna performance when a plurality of antenna elements is present, and for which a housing can be made thinner. Among paths between a first power supply unit 13 and a second power supply unit 14 provided at edges of a notched part 17 of a circuit board, a ground pattern of a path with a short electrical length relative to a wavelength of an operating frequency of a first wireless unit 15 or an operating frequency of a second wireless unit 16 is split to give an electrically unconnected state. In this way, ground current caused by one of the antenna elements (for example, second antenna element 12) will not flow to or will be reduced in the other antenna element (for example, first antenna element 11), so that deterioration in the characteristics of the other antenna element can be kept low.
