PURPOSE: An electric oven is provided to quickly transmit heat of a heat source to the inside of a cooking chamber, to minimize the preheating time or the cooking time, and to keep the internal temperature of the cooking chamber uniform during cooking. CONSTITUTION: An electric oven comprises an outer case(30) constituting the exterior; a cavity(32) installed inside the outer case; walking coil parts(38,40,40') disposed to a position corresponding to at least one of each surface of the cavity except a surface corresponding to a door(34); and plural heaters(44,46) disposed to positions corresponding to the surfaces of the cavity except the surface corresponding to the door and the surfaces with the walking coil parts. A cooking chamber selectively opened and shut by the door is formed in the cavity. The cavity comprises a magnetic material. The walking coil parts heat the cavity in an inductive heating method.
