Induction heating containers for electromagnetic generators that use this type of high-frequency method cannot achieve induction heating unless they are made of ferromagnetic materials such as iron, and those made of non-magnetic materials such as aluminum (alloy). In order to use this container as the above-mentioned induction heating container, it is necessary to fix a heating plate made of a ferromagnetic material to a part of the container body (usually the bottom surface). However, if the container body and the heat generating plate are carelessly fixed by common welding means, a space will be created between them, and this space will impede heat conduction from the heat generating plate to the container body. . As a result, even though the container body is made of a material such as aluminum (alloy) with high thermal conductivity, the thermal efficiency is significantly reduced when used as a cooking container or the like.

In view of these conventional circumstances, the present invention has been developed to improve heat conduction from a heat generating plate made of a ferromagnetic material to a container body made of a material with high thermal conductivity such as aluminum (alloy).
