PROBLEM TO BE SOLVED: To provide a radio communication terminal that performs authentication processing on two wireless communications networks that adopt different authentication systems, while maintaining high security. SOLUTION: The radio communication terminal 1 includes a first radio communication section 3, corresponding to a first wireless communication network 2; a second radio communication section 5 corresponding to a second wireless communications network 4; and an authentication processing section 6 for performing authentication processing with the second wireless communications network 4. When instruction for connection to the first wireless network 2 is received, the first radio communication section 3 forms a transmission line with the first wireless communications network 2 and performs authentication processing by means of a posterior terminal 7. Thereafter, in order to perform authentication processing with the second wireless communication network 4, the authentication processing section 6 acquires authentication information used for authentication processing with the first wireless communications network 2 from the posterior terminal 7 and performs authentication processing with the second wireless communications network 4 via the posterior terminal 7 and the transmission line.
