An induction cooking appliance comprising: a heating coil which is arranged below a top plate for mounting a to-be-heated object so as to inductively heat the to-be-heated object; a control circuit, including a heat generating component, for generating and controlling a high frequency current to supply to the heating coil; a blower device for taking in a cooling wind from an intake port, blowing the cooling wind to the control circuit, and discharging the cooling wind from an exhaust port; and a main case, which configures an outer appearance with the top plate, in which the heating coil, the control circuit, and the blower device are arranged; wherein the main case includes a first side surface wall arranged to face a flow of the cooling wind sent from the intake port to the control circuit; and the induction cooking appliance is configured so that in the main case, after the cooling wind taken in from the intake port formed at a portion other than the first side surface wall cools the control circuit, the cooling wind be flowed along the first side surface wall, and then the cooling wind be exhausted from the exhaust port formed at a portion other than the first side surface wall, characterized by the following features: a sub-case having an upper side opened is accommodated in an internal space of the main case, the control circuit and the blower device being arranged inside the sub-case; and a first exhaust flow path is formed between the first side surface wall and a side surface wall of the sub-case facing the first side surface wall, and is formed inside the internal space so that the cooling wind after cooling the control circuit contacts the side surface wall and flows in a constant direction through the first exhaust flow path. a heating coil which is arranged below a top plate for mounting a to-be-heated object so as to inductively heat the to-be-heated object; a control circuit, including a heat generating component, for generating and controlling a high frequency current to supply to the heating coil; a blower device for taking in a cooling wind from an intake port, blowing the cooling wind to the control circuit, and discharging the cooling wind from an exhaust port; and a main case, which configures an outer appearance with the top plate, in which the heating coil, the control circuit, and the blower device are arranged; wherein the main case includes a first side surface wall arranged to face a flow of the cooling wind sent from the intake port to the control circuit; and the induction cooking appliance is configured so that in the main case, after the cooling wind taken in from the intake port formed at a portion other than the first side surface wall cools the control circuit, the cooling wind be flowed along the first side surface wall, and then the cooling wind be exhausted from the exhaust port formed at a portion other than the first side surface wall, a sub-case having an upper side opened is accommodated in an internal space of the main case, the control circuit and the blower device being arranged inside the sub-case; and a first exhaust flow path is formed between the first side surface wall and a side surface wall of the sub-case facing the first side surface wall, and is formed inside the internal space so that the cooling wind after cooling the control circuit contacts the side surface wall and flows in a constant direction through the first exhaust flow path.
