An induction heating device includes a top plate (2) on which a cooking container is placed, an infrared ray sensor (3) configured to detect an infrared ray radiated from the cooking container through the top plate, a heating coil (4) to which a high-frequency electric current is supplied to generate an induction magnetic field for heating the cooking container, a mounting plate (6) on which a member for supporting the heating coil is mounted, and a heating control unit (8) configured to control an electric power for heating the cooking container by controlling the high-frequency electric current supplied to the heating coil based on an amount of an energy of the infrared ray received by the infrared ray sensor. The infrared ray sensor is thermally connected to the mounting plate.
