A sliding-type portable terminal is provided. The sliding-type portable terminal includes a first housing and a second housing. The second housing faces the first housing and can slide relative to the first housing. The sliding-type portable terminal also includes a pair of link members coupled with the first housing and the second housing. The link members rotate relative to one of the first and second housings. Also provided is a first guide opening formed on the other housing wherein one end of the link members is engaged with the first guide opening so as to move along the first guide opening as the second housing slides. In the sliding-type portable terminal, a pair of housings can be rotatably coupled with each other by means of the link members so as to sufficiently secure a greater range of sliding, and thus a space for mounting an input device, such as a keypad, or the like, is increased.
