PROBLEM TO BE SOLVED: To inexpensively manufacture with a simple structure by constituting a cooker body and a heating chamber only by three members obtained by bending one respective metal plates. SOLUTION: Respective one metal plates are each bent in a U shape to a first structure 1, a second structure 6 and a third structure 10. The first structure has a body front wall 3 having a front surface opening 2 opened and closed by a door, a body rear wall 4 and a body coupling wall 5 for coupling the walls 3, 4. The structure 6 has a body left side wall 7, a body right side wall 8 and a body upper wall 9, and is provided at a position where the wall 5 is not disposed between the walls 3 and 4. The structure 10 has a heating chamber left side wall 11, a heating chamber right side wall 12 and a heating chamber upper wall 13, and a heating chamber 14 and an electric equipment chamber 15 are partitioned by the body. The first structure is coupled to the second structure by spot welding or caulking. The third structure is coupled to the first and second structures by clamping with screws or the like.
