A mobile communication terminal is provided whose operability is improved by enabling a user to promptly use a function that the user requires, upon suspension of execution of an application program. A mobile communication terminal (mobile phone) 20 includes an output unit 216 having a liquid crystal display (LCD) 27 that displays an image; a main control unit 215 that controls the output unit 216; and an application program executing and managing unit 214 that executes an application program registered by a user. The application program executing and managing unit 214 sends a function transition request instruction (screen transition request instruction) to make a transition to a function specified by the application program, to the main control unit 215, upon suspension of execution of the application program. Based on the function transition request instruction (screen transition request instruction), the main control unit 215 controls the output unit 216 to display an initial screen of the function or a menu screen for selecting the function.
