  • adhesive part 21B has width or side-to-side dimension W2.
  • Above-described adhesive part 21A of heating cooker 2 covers a first (left) area extending from peripheral border 27 of lower wall 16 to gap 72 between left side wall 12A and first wall part 60, while above-described adhesive part 21B covers a second (right) area extending from peripheral border 27 of lower wall 16 to gap 74 between right side wall 12B and first wall part 60. Therefore, the failures of the internal components of heating cooker 2 are preventable, and heating cooker 2 has the improved reliability.
  • Support wall 17 includes fourth wall part 65 along its front (that is to say, on a front side in the drawing). Fourth wall part 65 is closest to door 8 and continuously extends from above-described first wall parts 60. As with first wall parts 60, fourth wall part 65 is joined to lower wall 16 by an adhesive part.
  • FIG. 16 illustrates an enlarged section of a portion around adhesive part 77 joining fourth wall part 65 and lower wall 16 together.
  • adhesive part 77 joins peripheral border 27 of lower wall 16 and support wall 17 together and has width or side-to-side dimension W3.
  • adhesive parts 21A and 21B correspond respectively to the first area and the second area
  • adhesive part 77 corresponds to a third area that extends in a side to side direction, connecting the first area and the second area.
  • width W1 of the first area and width W2 of the second area are equally set greater than width W3 of the third area. Securing the sufficient side-to-side dimensions for adhesive parts 21A and 21B enables more reliable sealing of gap 72 between side wall 12A and first wall part 60 and more reliable sealing of gap 74 between side wall 12B and first wall part 60.
  • the present disclosure is applicable to any heating cooker that uses heat to cook a heating target.
