It is an object of the invention to provide a portable wireless apparatus capable of maintaining high quality of a communication in various using configurations obtained by a two-axis hinge mechanism.A portable wireless apparatus (100) having a two-axis hinge portion includes a first antenna (102) which is suitable for a talking state and a second antenna (104) which is suitable for a waiting state. The first antenna (102) or the second antenna (104) is selected based on a result of opening/closing detection decided from an angle α of a first axis (106) and the result of opening/closing detection decided from an angle β of a second axis (107). Consequently, it is possible to select either of the antennas which is not influenced by hands or fingers of a user.
