It is possible to prevent the heat conduction efficiency from the magnetic plate 3 to the cooking board 4 from being lowered, and to prevent the magnetic plate 3 from falling off and becoming a defective product. When the bottom of the cooking board 4 is widened substantially over the entire area as shown in FIGS. 1 to 7, there is an advantage that the center of the cooking board 4 and the like can be sandwiched to prevent floating. In addition, since it is on the lower surface side of the cooking board 4, it does not affect the cooking surface 4a. In addition, no special member is required for this purpose.

In molding, the magnetic member is placed on the cooker after molding in the mold.
Position it at the position exposed on the bottom surface and
The side that becomes the lower surface after molding a part where the through hole is provided is also
While floating from the mold surface, perform the mold molding, and
Is exposed on the bottom surface of the bottom and has a through hole for the magnetic member.

It is inserted into a part of the cooking
Which part of the magnetic member
However, if necessary, insert it into a part of the cooking board that is molded
Enough to allow the magnetic material to float and fall off the cooking board
Heat can be prevented from flowing from the magnetic member to the cooking board
Efficiency is reduced, and the magnetic material comes off and becomes defective.
It can prevent snarling, especially when the magnetic member is wide.
If you want to make something, put it in the middle etc.
There is an advantage that floating can be prevented. Moreover, the lower side of the cooking board
Because it does not affect the cooking surface and is usually used for appearance
Since it is not provided, it can be provided in any form. And that
