A wireless apparatus having a foldable structure allowing improved antenna condition when opened with improved convenience is disclosed. A first housing and a second housing coupled by a hinge are freely opened and closed around the hinge. An antenna section for use in wireless communication is coupled to the first and second housings by the hinge such that the antenna section is situated at back of the second housing and is freely opened and closed around the hinge with respect to the second housing. A spring force is applied to the antenna section to rotate it in an opening direction. The antenna section is latched by an antenna latch member to be kept in a closed state. When the first housing and the second housing are opened to a predetermined angle, the latch is released to open the antenna section away from the second housing.
