Why does the cord of an electric heater NOT glow while the heating element does

Thus, the heating element becomes hot and glows red. On the other hand, the cords are made up of good conductors like copper. They have low resistance, and do not produce much heat when same amount of current is passed through it. Hence, the cord does not glow.
