The time interval selection unit selects a second time interval among second time intervals included in each first time interval. The control unit controls the transmitting unit and the receiving unit to operate, during the selected second time interval, in a first operational state in which a transmission of a connection request signal and a wait for reception of a response signal are repeatedly performed, and to operate, during each of the second time intervals other than the selected second time interval, in a second operational state in which a wait for reception of a connection request signal transmitted by another apparatus is performed for a third time interval shorter than each of the second time intervals.
