Claim 0:
1. An induction heating cooking apparatus, comprising:
a countertop configured to have a plurality of cooking areas in which a cooking container is seatable;
a plurality of coils configured to be provided under the countertop respectively for each cooking area of the plurality of cooking areas;
a plurality of inverters configured to be provided on a main substrate and respectively connected to each coil of the plurality of coils;
a plurality of noise filters configured to comprise a capacitor connected in parallel to an external power supply, respectively, and provide each inverter of the plurality of inverters with a voltage of the external power supply from which noise is removed;
a plug configured to be connected to the external power supply; and
an auxiliary substrate configured to be provided between the plug and the main substrate,
wherein the auxiliary substrate comprises:
an input terminal configured to be connected to a power supply line from the plug,
a plurality of output terminals configured to be branched from the input terminal to correspond to a number of the plurality of noise filters, and be connected to the power supply line facing each noise filter of the plurality of noise filters, and
a discharge circuit part configured to be provided between the input terminal and the plurality of output terminals and comprise a discharge resistor for discharging a voltage stored in the capacitor in response to a cutoff of the provided voltage of the external power supply.
