A portable terminal includes a first substrate (241), a circuit pattern unit (242) formed on an upper surface of the first substrate to configure a circuit, the circuit pattern unit having at least one dome contact portion (242a,242b) and a second substrate (243) laminated on the circuit pattern unit and having at least one dome mounting groove (244) to expose the dome contact portion and having a conductive dome (230) formed to be contactable with the dome contact portion, whereby a thickness of a printed circuit board used in an input device of the portable terminal can be reduced. |
