PURPOSE: An electric wok and a manufacturing method thereof are provided to maximize heat transfer efficiency by minimizing the heat loss of a heater because a body of the electric wok and the heater are formed into a single body by a centrifugal casting method. CONSTITUTION: An electric wok(10) comprises a body part(100) and a heater(200). The body part comprises a handle installation part(110) and a power supply part coupling part(120). The body part and the heater are formed into a single body. A heater insertion part(150) surrounding the outer circumference of the heater is formed in the lower part of the body part. A handle(130) is installed in the handle installation part. A power supply part is coupled to the power supply part coupling part. The heater is inserted in the heater insertion part and is made of a steel pipe. |
