PROBLEM TO BE SOLVED: To provide an electromagnetic steel sheet with such magnetic properties as to be extremely little degraded even after the steel sheet has been helical-worked. SOLUTION: The electromagnetic steel sheet comprises, by wt.%, 0.05% or less C, 4% or less Si, 0.2% or less P, 0.05-1% Mn, 2% or less Al and the balance substantially Fe; and has an n-value (a work hardening factor) of 0.18 or more in a strain range of 1% to 10% in a tensile test.
