A mobile terminal apparatus includes a first housing (1) provided with a display, a second housing (2) provided with a keyboard, and a slide holding mechanism (3) including a rail unit (5) provided in the first housing and including rail parts (4) extending in a sliding direction, arm members (9), rotation-slide connection members (10) which include rotation shafts separated from each other in the sliding direction and which connect one end portions of the arm members to the rail parts, and rotation connection members (11) which include rotation shafts separated from each other in the sliding direction and which connect the other end portions of the arm members to the second housing. The slide holding mechanism holds the housings such that the housings are slidable between a closed state in which the housings substantially entirely overlap and an open state in which the display unit and the keyboard are positioned on substantially the same plane.
