Abstract: A microwave oven door includes a shielding panel, which is made of a material through which microwaves cannot pass, having a contact section that opposes a front panel of the oven when the door is closed. A plurality of slits arranged in the contact section and/or the front panel, or both, prevent microwaves from leaking out through a gap formed between the front panel and the contact section. The slits are arranged in at least one row shaped as a closed loop and are evenly spaced from each other. The length of each slit corresponds to about 1/2 of a wavelength of a microwave, and the width of each slit corresponds to no more than 1/16 of the wavelength of the microwave. The interval between two adjacent slits corresponds to no more than 1/16 of the wavelength of the cooking microwave.
