A radio communication method executed by a radio communication apparatus (100, 100a) performing radio communication based on either role, a master or a slave, the master having authority to take control of radio communication with connection of the radio communication established and the slave wirelessly communicating under the control of the master with the connection of the radio communication established, the radio communication method, including: a role change reception step of receiving a role change request from a slave to a master when the radio communication apparatus (100, 100a) has a role of slave and has established connection to another radio communication apparatus operating as a master; and a reception step of scanning for, when the change request is received in the role change reception step, identification information transmitted from the other radio communication apparatus by predetermined multiple channels that are different from channels for use in the communication after the connection of the radio communication, and then receiving the identification information; and a disconnection step of disconnecting the radio communication with the other radio communication apparatus when the role change request is received in the role change reception step, wherein the identification information is information transmitted from the other radio communication apparatus information indicating that the other radio communication apparatus requests connection of radio communication, and information used for determining a partner for which the radio communication apparatuses (100, 100a) establishes the radio communication connection, the reception step includes scanning for, until the identification information has been received via a given channel of the multiple channels or a predetermined time has elapsed, the identification information and then receiving the identification information to establish new radio communication connection after disconnection of the radio communication connection, the identification information being transmitted from the other radio communication apparatus the scanning being with a longer interval of time of scanning for the identification information via the given channel of the multiple channels than when the change request is not received in the role change reception step or the scanning being at a higher frequency of scanning for the identification information on the given channel of the multiple channels than a frequency of scanning for the identification information on the non-given channel, that is a channel other than the given channel among the multiple channels, and after reception of the identification information, the radio communication apparatus (100, 100a) establishes the new radio communication connection to the other radio communication apparatus and functions as the master after establishment of the new radio communication connection. a role change reception step of receiving a role change request from a slave to a master when the radio communication apparatus (100, 100a) has a role of slave and has established connection to another radio communication apparatus operating as a master;
