<p>The mobile phone (1a) includes a lower housing (10) having one end (10a) and the other end (10b), an upper housing (20) having one end (20a) pivotally connected to the lower housing (10), and a monopole antenna (30) accommodated close to one end (10a) of the lower housing (10). The other end of the upper housing (20) pivots toward and away from the other end (10b) of the lower housing (10). The mobile phone (1a) is used in close proximity to a user's head with the other end (20b) of the upper housing (20) being distanced from the other end (10b) of the lower housing (10). Upon use, the lower housing (10) is disposed relative to the upper housing (20) so that the upper housing (20) intervenes between the monopole antenna (30) and the user's head (100). <IMAGE></p>
