Abstract
A high frequency heating apparatus of the present invention includes an inverter power supply for driving the high frequency generating device, a holding member for holding the inverter power supply and cooling fan for cooling down the inverter power supply. The holding member is provided with a holding portion for holding the inverter power supply and an air guide portion for guiding cooling air from the cooling fan toward the inverter power supply, and the air guide portion covers the inverter power supply and guides the cooling air in a manner that a semiconductor switching device and a high voltage transformer of the inverter power supply are primarily cooled down.
