PURPOSE: A keypad assembly of a mobile communication terminal is provided to protrude upper sides of key button units in predetermined height on a surface of a front case, and to form projections on the upper sides of the key button units, thereby easily operating key buttons and enabling the visually impaired to easily operate the key buttons. CONSTITUTION: An assembly of a keypad(132) is installed between a PCB(140) and a front case(120). The PCB(140) has many metal domes(141) on an upper side. The front case(120) forms many key holes(121). Contact projections(133) are protruded on the keypad(132) in lower direction of key button units(131) such that upper parts of the key button units(131) can be protruded in predetermined height 'h1' on a surface of the front case(120). The key button units(131) are protruded on an upper side of the keypad(132) in order to be inserted into the key holes(121).
