PURPOSE: A mobile terminal having a hard key is provided to install a hard key capable of sensitively detecting changes of a magnetic field for sensitive operation, even when a user does not press the hard key completely. CONSTITUTION: A mobile terminal includes a metallic dome (11) having elastic force; and a printed circuit board (12) in which the metallic dome is installed. A magnetic field is formed in the dome and the printed circuit board. The printed circuit board includes a first pattern formed thereon, for mounting the dome thereon by soldering; and a second pattern formed thereon for detecting a contact with the dome. A first pattern and a second pattern are formed in for mounting the dome thereon by soldering.
