PROBLEM TO BE SOLVED: To solve problems of conventional pots for electromagnetic cookers that thermal and mechanical strength are not sufficient because a heating element is baked outside of the pot bottom and a heat-resistant coating material is applied thereon, and to provide a structure capable of securing strength. SOLUTION: Shallow flat recessed bottoms are formed on the pot bottom, metallic plates for heating are inserted thereto and covered with a lid, and the lid is bonded to the pot bottom using a heat-resistant adhesive. Gaps between the metallic plates inserted between the lid and the recessed bottoms are filled with particles of a heat-resistant material. Thus, forces generated by expansion and shrinkage of the metallic plates for heating do not affect a pot wall, and a glaze is applied on the outer surface and baked as a substitute for the coating material. |
