PROBLEM TO BE SOLVED: To provide a heating cooker capable of reducing radio wave leakage from an arm attached to a door, effectively.SOLUTION: At a part A close to a first arm 51, a notch 43 is not provided between the adjoining vertical surfaces 45, 45 of a periodic structure 36 thus reducing microwaves, reaching the peripheral structure 36 from a heating chamber 14, from leaking to other part via a first arm 51. At a part other than the part close to the first arm 51, notches 43 are formed between the adjoining vertical surfaces 45, 45 of a periodic structure 36, at a predetermined interval, thus attenuating the microwaves advancing in the longitudinal direction of the peripheral structure 36.SELECTED DRAWING: Figure 10 |
