    • A mobile terminal is disclosed, by which the feel of manipulation of a mobile terminal keypad is enhanced and by which brightness deviation of keypad illumination is minimized. The present invention includes at least one or more light sources, a keypad having a plurality of manipulating buttons, each having a button protrusion provided to a bottom of the corresponding manipulating button, a light guide film configured to have light provided by the at least one light source enter a lateral side thereof, the light guide film having a plurality of insertion holes configured to have the button protrusions pass through, respectively, and a printed circuit board having a dome switch pressurized by the button protrusion of the keypad and an electrode part selectively coming contact with the dome switch, wherein a width of at least one of the insertion holes provided to the light guide film is different from a length thereof.
