摘要： A RF module generates a high-frequency transmission signal. An inclination sensor detects an inclination of a computer to detect that an antenna is set in a state where the antenna may come close to a user's body. A mode sensor detects that a first housing unit is closed by facing other main plane of a first housing unit and one main plane of the second housing unit. A control circuit generates a switching signal when a detection signal is not less than a predetermined level, in a case where the mode sensor detects that the first housing unit is closed by facing other main plane of the first housing unit and one main plane of the second housing unit, and concurrently where the antenna is set in the state where the antenna may come close to a user's body. A switching circuit outputs, to the antenna, the high-frequency transmission signal after relatively attenuating the high-frequency transmission signal in comparison with the high-frequency transmission signal in the case where the switching signal is not inputted, in a case where the switching signal is inputted to the switching circuit from the control circuit.
