Abstract: Provided is a terminal. The terminal comprises a shell and a PCB arranged inside the shell, and the PCB is arranged in the middle of the shell. The terminal further comprises: two cells arranged inside the shell, distributed on two sides of the PCB, and close to the PCB; and a thermally conductive component arranged inside the shell, the middle of the thermally conductive component being connected to the PCB, and two ends thereof respectively extending into areas of the cells. According to the terminal in the present invention, the PCB is arranged in the middle of the shell, the two cells are arranged on the two sides of the PCB, and the thermally conductive component is arranged between the PCB and the two cells, so that when the terminal is in use, heat generated by the cells is much less than the heat generated by the PCB, and therefore, the cells are cold areas relative to the PCB, and the heat generated by the PCB is conducted to cell areas on the two sides via the thermally conductive component, thereby preventing a hot stack forming in a PCB area, ensuring that a housing does not become hot easily, allowing a good holding feeling for the hand, and ensuring the performance experience for a user during use.
