力を得るのが限度であった。SUMMARY OF THE INVENTION As mentioned above, stainless steel, which is used as a component of microwave ovens, absorbs microwaves because of its large volume resistance, relative magnetic permeability, and surface resistance. Therefore, a part of the microwave is wasted due to the heat generation effect on the inner surface of the oven, resulting in a problem that the efficiency of irradiating the microwave to the food to be cooked is reduced and the output loss is large. For general household use, due to constraints on power supply capacity, even if the installation position of the microwave generation source or the shape of the inner surface of the oven were taken into account, the output power was around 800 W.

The reason for this is that it is composed of an inner layer metal body having low volume resistance, relative magnetic permeability, and surface resistance. The inner layer metal body is preferably made of copper or aluminum, and is laminated on the outer layer metal body by plating, thermal bonding, vapor deposition, or the like.

The container part B has an open front and top surface, and an inner layer metal body 2 made of copper or aluminum is formed on the inner surface of an outer layer metal body 3 made of stainless steel. A top plate portion C, in which the body 4 is laminated and formed in close contact with each other, is integrally formed by crimping the flange portion B1 of the container portion B and the outer peripheral portion of the top plate portion C. Therefore, the thickness of the inner layer metal body 2 is the total thickness of the outer layer metal body 1 and the inner layer metal body 2 (approximately 0.4
mm), it is set to 5 to 10μ.

The microwave loss (heat loss) on the metal surface is correlated with the surface resistance Rs, and the larger the value of Rs, the more
Microwave loss increases. Therefore, it can be seen that copper and aluminum are more suitable as constituent materials for ovens than stainless steel, and Table 2 shows experimental comparative examples.

とができる。Effects of the Invention The present invention provides a microwave oven with a two-layer structure consisting of an outer layer metal body made of stainless steel and an inner layer metal body whose volume resistance, relative magnetic permeability, and surface resistance are smaller than that of the outer layer metal body. Therefore, the outer layer metal body maintains corrosion resistance, the inner layer metal body suppresses loss due to heat generation of microwaves on the surface of the inner layer metal body, and output and heating efficiency can be significantly improved.
