Abstract: A cellular phone 100 registers incoming call histories in which other party telephone numbers are correlated to own telephone numbers which received a call in an incoming call history accommodation section 14b. It is judged whether or not the other party telephone number to which a call is made is the other party telephone number from which a call was received previously with reference to the incoming call histories when transmitting a call. If the other party telephone number is an other party telephone number which was received previously, the own telephone number which was used at that time is extracted from the incoming call histories and a call transmission is made. Accordingly, this enables preventing the error in using different plurality of own telephone numbers.
