A locking notch 112 to be locked is formed. An attachment fitting 113 for fixing the case 110 to the support fitting 103 with screws 114 is fixed to the lower side of the notch 111 on the side wall of the case 110.

  Further, a pressing plate 115 that is engaged with the bottom surface of the peripheral edge of the stepped opening T1 of the table T is attached to the side wall of the case 110 so as to be adjustable in the vertical direction. The holding plate 115 is locked to the bottom surface of the peripheral edge of the stepped opening T1 of the table T so that the top plate 101 does not float from the table T when a force to move the case 110 upward is applied. This is to prevent the caulking material between the plate 101 and the table T from peeling off.

  In this heating cooker 100, an operation of removing the case 110 from the top plate 101 for maintenance of the induction heating unit will be described. First, the screw 114 of the mounting bracket 113 of the case 110 attached to the support bracket 103 of the top plate 101 is removed. When the screw 114 is removed, the case 110 does not fall because the locking notch 112 of the notch 111 is locked by the support fitting 103. Thereby, when removing the screw 114, it is not necessary to work while supporting the case 110. After removing the screw 114, the case 110 is slightly slid forward until the support fitting 103 is not locked to the locking notch 112 of the notch 111, and the case 110 is removed downward.
