Abstract
A rare earth element contained substrate for heat generating device contains the rare earth elements, compounds of the rare earth elements, or rare earth minerals so as to heighten its withstanding temperature and improve its heat dissipation. The substrate is also able to radiate a far infrared ray and yield negative ions for purifying the air.
