Abstract
By producing a composition comprising by mass% 0.007% or less of C 4 to 10% of Si and 0.005 to 1.0% of Mn with Fe and inevitable impurities as the balance and by bringing the sheet thickness to between 0.01 and 0.10 mm and the cross section roughness Pa to 1.0 µm or less there is no degradation of magnetic properties and it is possible to realize iron loss properties such that degradation of the space factor is avoided even when an electromagnetic steel sheet having a sheet thickness of 0.10 mm or less has been subjected to siliconizing in order to increase the Si content of the steel.
