To provide a mobile communication terminal capable of providing stability of electric field strength to a user.

The mobile communication terminal transmits/receives information via a mobile communication network, and includes: an electric field state information control section 21 that decides the electric field strength stability depending on whether or not the strength of received electric field is a prescribed level or more and generates electric field stability data 41; a storage section 4 for storing the electric field stability data 41; an in-zone timer 51 for counting a prescribed time after storing the electric field stability data 41 to the storage section 4; and a display section 32 for exhibiting the strength of the received electric field and the electric field strength stability to the user, and when the in-zone timer 51 expires without the reception electric field strength decreased less than the prescribed level, the mobile communication terminal increases the level of the electric field strength stability to update the electric field stability data 41.
