A mobile communication terminal is provided to be applied to a product of which a vertical space within a main body is small by enabling the first knob to move right/left and easily separate a battery pack from the main body by enabling a hook to move up/down by operating force of the first knob, thereby reducing the damage of the terminal. A mobile communication terminal(1) comprises the followings: a main body(10); a battery pack which is mounted on the main body(10) and in which a locking groove is formed; and a locking device(30) which is prepared in the main body(10) and maintains/releases its state of being locked with the locking groove. The locking device(30) comprises the followings: the first knob(31) which is installed in the main body(10) to move right/left and has a projection(35) in its rear; and the second knob(36) which is installed in a lower side of the first knob(31) to move up/down, and has a slot(37), inclined so that the projection(35) can be guided, and a hook for maintaining or releasing its state of being locked with the locking groove when the first knob(31) moves.
