A mobile telephone terminal has a configuration in which it is possible to prevent a wrong operation of the mobile phone terminal due to an unconscious touch with a touch panel during a telephone call without restricting available function during the telephone call. That is, the mobile telephone terminal includes a touch panel unit 104 for inputting information and a telephone call determining means 201 which judges whether the mobile telephone terminal is in a telephone call mode. Furthermore, the mobile phone terminal includes an approach detecting means 202 which outputs a wave and detects receiving of the wave as approaching of an object. Furthermore, the mobile phone terminal includes an input controlling means 203 which carries out a control to make information, which is inputted from the touch panel unit 104, ineffective in the case that the telephone call determining means 201 judges that the mobile phone terminal is in the telephone call mode and the approach detecting means 202 detects approaching of the object.
