HIGH-FREQUENCY HEATING DEVICE
A high-frequency heating device includes: a heating chamber configured to heat a food; a high-frequency generating unit configured to supply high frequency waves to the heating chamber; a driving power supply configured to drive the high-frequency generating unit; a cooling fan configured to cool the high-frequency generating unit and the driving power supply; an air guide serving as a blast guide of the cooling fan; and a noise filter configured to suppress a noise generated from the high-frequency generating unit and the driving power supply. The noise filter is attached on a cooling fan side of the air guide. A plurality of cooling holes are formed on a partition wall between a component mounting surface of a noise filter substrate and the air guide.
