PURPOSE: A mobile communication terminal comprising touch sensors on key buttons and a key signal inputting method using the mobile communication terminal are provided to install touch sensors on key buttons for selecting a menu displayed on a screen or inputting data, and to supply the menu by distinguishing an input signal produced when a key button is pressed from an input signal produced when the key button is touched, thereby reducing the number of pressing times of the key buttons. CONSTITUTION: A key input unit(30) comprises plural key buttons. A touch sensor(50) is installed on each key button, and senses a key button touch of a user. A controller(10) supplies a menu corresponding to a key button according to a signal inputted by pressing the key button and a touch signal sensed from the touch sensor(50). A memory(20) stores lower menus corresponding to the plural key buttons, respectively, and stores a program and data for displaying the touch signal and the inputted signal on a display(40) under control of the controller(10).
