<p>Provided is a mobile terminal which can be switched to a longitudinal state or a lateral state without degrading the appearance of the mobile terminal. A rotary side case can be stably supported so that the mobile terminal (1) can be switched from the longitudinal state to the lateral state or from the lateral state to the longitudinal state via a rotary support mechanism (10). An opening (25) is formed at an intermediate position in the thickness direction of the side surface of a rotary side case (3) for movement allowing the movement of the rotary support mechanism (10) to move.</p>
