Abstract
Disclosed herein is a carbon heater. The carbon heater comprises a carbon filament disposed in a tube for serving as a heating element. The carbon filament has support parts integrally formed at the carbon filament while being protruded from the carbon filament in the direction perpendicular to the longitudinal direction of the carbon filament such that the support parts are supported inside the tube. Consequently, the carbon filament is more stably supported in the tube by the support parts, whereby the service life of the carbon heater is increased, and easy and convenient design and assembly of the carbon heater is accomplished.
