PROBLEM TO BE SOLVED: To provide a heating cooker in which an internal capacity inside a cooking chamber can be increased while a reduction of a product in size is being achieved.SOLUTION: On a peripheral portion of a door 3, a frame-like ridge 144 attenuating radio waves from a cooking chamber 14 is provided. The ridge 144 has a recess-shaped choke groove 148 and a conductor piece 152 extending at an opening side of the choke groove 148 and being periodically arranged. Within a rang where a radio wave leak amount from the cooking chamber 14 is equal to an evaluation reference value or less, an overhanging surface portion 156 of the conductor piece 152 facing an oven front plate 12 and having a width dimension d2 different from those of an upper side portion 144a, a lower side portion 144b, a left side portion 144c, and right side portion 144d of the ridge 144 is formed. On this account, a width dimension d4 of the oven front plate 12 facing the upper side portion 144a can be narrower than width dimensions d4 of the oven front plate 12 facing the lower side portion 144b, the left side portion 144c, and the right side portion 144d.SELECTED DRAWING: Figure 30
