PROBLEM TO BE SOLVED: To install a magnetic metal plate having a number of holes each having a standing part on one surface onto a bottom outer surface of a range for heating a container mainly comprising nonmagnetic metal as main material by electromagnetic waves. SOLUTION: For tightly applying a stainless steel plate 1 to a nonmagnetic metal plane for heating a cooker of nonmagnetic metal used in an electromagnetic range by electromagnetic waves, a number of hole parts 2 having standing parts 4 are provided in the stainless steel plate 1, where the standing parts 4 are formed in flower-opened form, with roundness of root parts 6 of the standing parts 4 set to be 1.5 times or more the plate thickness of the stainless steel plate 1, and the standing parts 4 of the stainless steel plate 1 are fitted into a bottom outer surface of the nonmagnetic metal plate. The form of the hole parts having the standing parts provided in the stainless steel plate 1 to achieve strong installation and tight adhesion of both metal surfaces can thus be provided. |
