To provide a heating cooker having a drawer-type automatic opening and closing door capable of reducing/eliminating influence (falling/leakage and the like) of a cooked object such as food caused by impact shock generated in opening and closing the door, by performing fine control in opening and closing the door.

When a specific position detecting means detects a stop front-side position (door full-opening switch Pso in full-opening, and intermediate switch Psi in full-closing) disposed in front of a stop position of the opening and closing door, a speed control means controls a driving means and reduces a moving speed of a drawer body. A position for automatically stopping the door (full-opening position Po, full-closing position Pc) with respect to the door opening and closing is confirmed in start and termination of cooking to control an opening and closing speed to the stop. As the sudden stop at the stop position, of the drawer body can be prevented, the impact shock in stopping can be reduced, and the influence on the cooked object such as food can be reduced/eliminated.
