To provide a complex heater enabled to obtain high temperature within a short period by using a carbon fiber heating element, having far- infrared ray effect, negative ion effect, deodorizing effect, and sterilization effect, utilized as a heat source for household cooking and heating apparatus, industry, cooking, medical treatment, heat insulation of clothes, or the like.

Flat rod-shaped carbon fiber heating elements (101) as a first heating element, and a cylinder-shaped carbon fiber heating element (102) as a second heating element are inserted and mounted inside a heat-resistant quartz glass tube (103), and both ends of those carbon fiber heating elements (101, 102) as the first and the second heating elements are fixed to molybdenum electrodes (104), and heat is radiated from the carbon fiber heating element within a short time by supplying electric power (105).
