Abstract
A magnetic steel sheet used for an alternating current core, and having excellent magnetic properties in both a rolling direction, and the direction perpendicular thereto, and a method of producing the magnetic steel sheet. The magnetic steel sheet in a recrystallized cold-rolled condition is characterized in that the intensity ratio of {100}<001> orientation to random orientation is 2.0 or more, the intensity ratio of {011}<100> orientation to random orientation thereof is 2.0 to 10.0, and the intensity ratio of <001>//ND orientation to random orientation is preferably 2.0 or less. The method of producing a magnetic steel sheet includes hot-rolling a silicon steel slab so that the intensity ratio of (015)[100] orientation to random orientation of the recrystallized hot-rolled sheet is 3.0 or more.
