PURPOSE: A twisted ceramic heater is provided to increase the durability of a ceramic heater and optimize the amount of emitting heat, thereby increasing energy efficiency. CONSTITUTION: A carbon heating object is embedded in a ceramic body(10). An upper cap(20) is densely coupled with the top of the ceramic body. A lower cap(30) is densely coupled with the bottom of the ceramic body. The section of at least protrusion has a semicircular shape. At least one electrical terminal unit(21) penetrates the top of the upper cap. |
