PURPOSE: A mobile terminal can have a blind layer not to show a dome switch through a gap between a side key and a case. CONSTITUTION: A side key (132) comprises a button portion receiving predetermined commands by a user. The side key is inserted into an opening part of a case. One side of a supplementary substrate (200) is located in the rear surface of the side key. The other side of the supplementary substrate is electrically connected with a printed circuit board. The supplementary substrate transmits an electrical signal to the printed circuit board when the button portion is pushed. |
