PURPOSE:To contrive to use a thinner plate as a material for an inner case and reduce cost by providing a bent piece formed by bending downwards the lower front face of an inner case body and a bent piece formed by fending downwards the front face of a bottom plate and fixing inner case body and the bottom plate by providing a gap between both bent pieces. CONSTITUTION:A bottom plate 34 forms in one body both side faces and a bottom face of a cooking chamber 32 in cross section of substantially U-shape by bending the bottom plate 34. The front face of the bottom face is bent downwards to form a bent piece A34a. A reflection plate 35 forms in one body the rear face and the upper face of the cooking chamber 32 and both side sections are bent and they are fixed to the inner plate by spot welding, etc. A bottom plate 36 is placed beneath the inner plate 34 to form in one body the bottom faces of the cooking chamber 32 and a control room 33. The front section of the bottom plate 36 is bent downwards to form a bent piece B36a and at the same time a gap is provided between the bent piece A34a and bent piece B36a to fix the inner plate 34 and the bottom plate 36 together by spot welding, etc. A water receiving pan 44 is held freely slidably between legs 34 and forms a concave section which is wider than the front opening. With this constitution, water drops developed during cooking flow surely to the water receiving pan 44 by means of a bent piece A, and the material for the bottom plate can be made of a general material which is low in resistance to rust and to provide an inexpensive inner case.
