PROBLEM TO BE SOLVED: To provide an induction heating cooker substantially reducing noises of a blast fan by effectively cooling a component part having a high heat generation amount. SOLUTION: The induction heating cooker is equipped with a wiring board, a circuit component mounted on the wiring board, a heat sink fixed to the circuit component, a chamber storing the circuit component and the heat sink and including an inlet and an outlet, and a blast fan supplying air to the inlet of the chamber and forming air flow in the chamber. A given cross-section of the chamber has substantially the same width with the heat sink. With this, the air flow flowing in the chamber is not dispersed in all directions but intensively flows along the heat sink (and a cooling fin) in the chamber, and the heat can be radiated extremely effectively, so that the number of revolutions of the blast fan (and a blast motor) can be reduced to substantially reduce the noise by those high-speed rotations.
