PROBLEM TO BE SOLVED: To provide a hands-free device with less number of components. SOLUTION: An address number denoting a storage location of a destination telephone number stored in a storage section MEM of a mobile phone HN is cross-referenced with a plurality of input means and the result is stored in a random access memory 34d provided to a control section 36 of the hands- free device 11 as registration data. When any of a plurality of the input means is operated, the control section 36 acquires an address number corresponding to the operated input means from the random access memory 36d and the address is supplied to the connected mobile phone HN, which makes dialing of the destination telephone number corresponding to the address number. Since the random access memory 36d stores no destination telephone number stored in the mobile phone HN but stores the address number, a storage means needing a high storage capacity is not required and number of components can be reduced.
