A mobile terminal holder includes a body configured to receive a mobile terminal mounted thereon, and a receiving portion provided in the body. The receiving portion is configured to receive a cooling element for heat-exchange with a mobile terminal mounted on the body. Even if the mobile terminal is used for a long period of time mounted on the holder, heat generated from the mobile terminal can be effectively dissipated. In this manner, defective operation of the mobile terminal, due to degradation in reliability of components resulting from temperature increase of the mobile terminal, can be prevented.
