This utility model publicizes a kind of new electric heating element belonging to far-infrared electric heating field. This new electric heating element is using micro-thin long carbon fibers are centralized and formed into a strand, then more than one carbon fiber strand are weaved into a long carbon fiber belt, further convolved into spiral item 2. Put spiral item 2 and two groups of transitional linking parts item 3, item 4, item 5 and item 6 into and are sealed in a hollow quartz glass pipe item 1, thus this electric heating element is formed. In the hollow part of sealed quartz glass pipe item 1, high-purity inert gas is filled as auxiliary thermal conduction medium. This makes the electric heating element own the following characters: high transformation rate for electricity and heat; rich far-infrared; large heat radiation energy; long service life time, etc. This kind of electric heating element can be widely applied in far-infrared physical therapy device and civil electric heater products.
