Abstract: In a built-in drawer type cooking device, an open/close door 2a and a heating container 2b that constitute a drawer body 2 are separably connected to each other. The open/close door 2a and the heating container 2b are connected via an insulator 10 to prevent a discharge phenomenon due to emission of microwaves. The open/close door 2a and the heating container 2b can be separated from each other with the drawer body 2 being drawn out, and thus the heating container 2b can be taken out of the cooking device and cleaned or wholly washed. An inner wall surface of a heating chamber 3 that is easily contaminated can be cleaned while being visually checked. The heating container 2b and the open/close door 2a are separately produced, and can be individually stored, conveyed and stacked, thereby reducing a rejection rate due to deformation and increasing productivity in an assembling process.
