[0014]

According to the present invention, a mobile phone having a first housing and a second housing joined by a hinge, a display portion in the first housing, and an operation portion in the second housing. In the wireless device, the second housing has an antenna projecting from a side surface of a connection between the wireless circuit and the first housing,
It becomes possible to make the weight distribution heavy on the side of the second housing having the operation unit. The center of gravity on the side of the operating unit improves the operational feeling of the operating unit, and since the antenna and the wireless circuit are arranged in the same housing, the connection between the antenna and the wireless circuit does not have to be via a hinge. The amount of wiring that passes through the hinge can be reduced.
