Abstract: The present disclosure relates to a cooking apparatus having a heating module capable of moving in a two-dimensional space and, particularly, to a cooking apparatus comprising: an upper plate configured to support a cooking vessel, a heating module disposed movably in a space provided under the upper plate and included a coil, and a rail disposed under the heating module to guide movements of the heating module, wherein electric current is supplied to the rail and the heating module supplies an alternating current through the rail. According to the present disclosure, the heating module supplies a current through the rail rather than receiving a current through a separate connection coil or wiring from an external power supply, thereby enabling shorting or disconnection of a current to be prevented even if the heating module moves.
