Abstract
There is provided a mobile wireless terminal in which characteristics such as improved antenna directivity of a built-in antenna and gains thereof are improved and downsizing is possible. The mobile wireless terminal comprises: an electrically conductive upper housing which contains an upper board; a lower housing which contains a lower board; and a hinge part which connects the upper housing and the lower housing to each other. An antenna element and an auxiliary metal fitting (a parasitic element) which are provided on the lower board are opposed to each other such that the antenna element and the auxiliary metal fitting each are electrostatically capacity-coupled with the upper housing by the hinge part. The auxiliary metal fitting and the antenna element are capable of changing the directivity since the auxiliary metal fitting and the antenna element are provided close to a part of the upper housing. As a result, antenna characteristics can be improved without sacrificing the design of outer appearance.
