なる発熱体を有する調理用器物が使用されている。2. Description of the Related Art Items used in an electromagnetic cooker are required to be made of a magnetic material that can be heated by electromagnetic induction. However, since the magnetic material is relatively expensive and heavy, it is not common to construct the entire container with the magnetic material. Therefore, a cooking utensil having a heating element made of a magnetic material is used only in a portion corresponding to a magnetic field generating coil of an electromagnetic cooker.

等の方法である。In such an electromagnetic cooking device having a heating element as a part, sufficient induction heating is not performed if the coil of the electromagnetic cooking device and the heating element of the cooking device are displaced from each other. Must always be placed in the position. Therefore, various methods have been proposed for determining the position of the electromagnetic cooker and the cooking utensil. For example, a method is possible in which a groove is provided in the electromagnetic cooker, a protrusion is provided at the bottom of the cooking utensil, and they are engaged with each other.

Can be formed,
In thermal spraying, it is difficult to apply a thick magnetic material, and it is difficult to form a heating element that can sufficiently perform heating by electromagnetic induction, which is unsuitable as an electromagnetic cooking utensil. Further, in the case of manufacturing a cooking utensil by joining a plate-shaped heating element and an instrument body, it is possible to secure a heating element having a sufficient thickness for induction heating, but after forming a protrusion on the instrument body. However, it is difficult to join the plate-shaped heating element, and the number of steps is increased when the protrusion is provided after joining the container body and the heating element.
