的に行うことが出来る利点があり、広く利用されている
。Microwave ovens generally cook food using high frequency waves of about 2450 MHz, and are widely used because they have the advantage of being able to cook quickly and hygienically.
このような電子レンジで高周波を利用して調理を行うと
きには、調理された食品には焦げ目が出来ない。When cooking using high frequency waves in such a microwave oven, the cooked food does not become brown.
したがって、例えばグラタン、ピザパイ、ギョウザ等の
食品のような焦げ目が必要とされるような場合には、電

る。（特公昭６０−１５５４８号広報参照）。Therefore, a layer of conductive elemental metal is provided on the bottom of the container, and when exposed to microwave radiation, said metal layer is heated.
It has been proposed to partially brown the food in the container and to form the metal layer into a thin film by vacuum deposition to eliminate the reflection of microwaves on the metal surface. (Refer to Special Public Relations Publication No. 15548/1983).
しかしながら、前記の従来の方法により、マイクロ波調
理容器を作製しようとする場合、容器壁面に直接導電性
金属元素を蒸着して、容器を作製することは、不可能で
はないが、採算がとれない方法である。However, when attempting to manufacture a microwave cooking container using the conventional method described above, it is not possible to manufacture the container by directly vapor depositing a conductive metal element on the wall of the container, but it is not profitable. It's a method.
そこで、ポリエステル等の基材フィルムに導電性金属元

理用容器を提供することにある。Therefore, the problem to be solved by the present invention is to provide a heating element layer on a base film by vapor deposition, sputtering, or printing, and then attach the base film provided with the heating element layer to the wall surface of the container. The object of the present invention is to provide a microwave cooking container that can be produced economically and efficiently and that does not cause spark ignition.

、本発明を完成したものである。[Means for solving the problem] As a result of research to solve the above problem, the present inventor found that the cause of spark ignition was that the base film supporting the heating element layer was damaged by the heat during microwave heating. As a result, the distribution of the material constituting the heating element layer becomes uneven, and the heating element layer is coated on the base film containing the heating element layer, and a reinforcing layer of non-woven fabric, etc. It was discovered that spark ignition could be eliminated by stacking the two layers, and based on this knowledge, the present invention was completed.
