<p>PROBLEM TO BE SOLVED: To enhance an antenna characteristic of a mobile wireless device provided with an antenna when the mobile wireless device is actually used. SOLUTION: A hinge section 40 turnably couples a device body case 20 and a cover case 30 of a mobile phone 10. Furthermore, the device body case 20 is made of a resin material, a metal or a material including the metal, and the cover case 30 is made of a metallic material. Furthermore, since the cover case 30 is placed on a side face of an antenna 50 when the mobile phone 10 is in use, a current easily flows through the cover case 30, and a current flowing through the device body case 20 is decreased so as to reduce disturbance in the current distribution when a user holds the device body case 20 in its hand, thereby reducing deterioration in the antenna gain.</p> |
