ABSTRACT:
This is a cooking utensil suitable for electromagnetic induction heating cooking apparatus. The cooking utensil is made firmly integral between an aluminum container body and an iron flame-sprayed layer by flame-spraying an iron layer which is a magnetic layer at least on the outer surface of the bottom of the container of aluminum or aluminum alloy in a manner to make corresponding portions of such iron layer penetrate into plural inclined grooves which have been formed on the outer surface of the bottom in advance, thereby enabling to utilize otherwise unsuitable aluminum material for the cooking utensil.
