Abstract
The invention provides a microwave oven capable of reducing the electromagnetic noises in the 2.45 GHz band generated during operation of the microwave oven. A microwave oven 1 including a microwave oven main body 2 having a heating chamber 3, and a door attached thereto. A ferrite sheet 14 disposed to cover the gap formed between the microwave oven main body 2 and the door 5 reduces the electric waves leaking through a choke groove 6 formed to a door panel 7. A punching metal plate 11 disposed on an outer side of a rear window film 10 and a wire mesh sheet 19 disposed on an inner side of a front window glass 13 shields the electric waves leaking through the window of the door 5, and the shielded electric waves are flown via a copper tape 20, an aluminum tape 17 and an EMI gasket 18 to a door case 8. Ferrite sheets 21 and 24 reduce the electric waves leaking through the gap of the door 5.
