## Abstract

A holder and a mobile terminal including the holder are disclosed. The holder is located in the mobile terminal, the holder includes a heat conduction area and a heat insulation area, the heat insulation area is close to an edge of the holder, the heat insulation area is adjacent to the heat conduction area, and a heat emitting element in the mobile terminal is proximate to the heat conduction area. The heat insulation area is provided on the holder, and the heat insulation area is close to the edge of the holder and is adjacent to the heat conduction area, so that, in a process of transferring heat in the heat conduction area to the edge of the holder, the heat is impeded by the heat insulation area, thereby reducing heat at the edge of the holder.
