PURPOSE: An electric hot blast heater using high frequency induction heat is provided to reduce consumption power in half, compared with an electric heater using a nichrome wire by increasing thermal efficiency using high temperature and reducing heat loss. CONSTITUTION: An electric hot blast heater using high frequency induction heat comprises a heating element(30). The heating element is heated by alternating current flux. The heating element is installed inside a box made of material which is strong against heat, such as quartz glass and ceramics. The heating element is made of iron with high heating efficiency or stainless material containing iron.
