Abstract
A mobile radio apparatus that achieves high radiation efficiency in various usage states of a foldable mobile radio apparatus without causing negative impact on communication, and that can realize a thin model. In this mobile radio apparatus that is foldable and that has a mechanism joining a first case and second case at a hinge part and allowing the mobile radio apparatus to open and close, flat conductor (), flat conductor () and flat conductor () that are placed distant from flat conductor () are placed in the first case, gravity sensor () detects an inclination angle of the mobile radio apparatus to judge the usage state of the mobile radio apparatus, and control section () controls high frequency switch () according to the inclination angle and supplies power selectively to flat conductor () and flat conductor (). Furthermore, power is constantly supplied to flat conductor () during communication at a different phase from the phase power is supplied to flat conductor () or flat conductor ().
