A mobile terminal is provided in which gaps between keys provided in a second main body change as a first main body moves. The mobile terminal includes a first main body; a second main body having a plurality of keys; and a hinge connecting the first main body and the second main body, wherein when the first main body opens from the second main body, the second main body extends and gaps between the plurality of keys are widened, and when the first main body closes on the second main body, the second main body retracts and the gaps between the plurality of keys are narrowed. Therefore, when the mobile terminal is opened, gaps between keys provided in the mobile terminal are widened and thus a user can more conveniently use the keys provided in the mobile terminal.
