Disclosed is a pop-up type portable terminal. The pop-up type portable terminal includes a main housing, a sub-housing slidably coupled to the main housing such that the sub-housing is slidably accommodated in or withdrawn from the main housing, a main board installed in the main housing, a guide beam fixed to one side of the main board and extending lengthwise along the main board, a guide rail installed at a rear surface of the sub-housing and extending lengthwise along the sub-housing so as to engage with the guide beam for guiding a sliding movement of the sub-housing, and a torsion coil spring installed in the main housing and having a first end portion fixedly coupled to the main housing and a second end portion fixedly coupled to the sub-housing in order to provide bias force in a direction urging the sub-housing to be withdrawn from the main housing. Noise caused by friction between the guide beam and the guide rail is thereby significantly reduced.
