A cast slab containing C: less than 0.02 mass % and made of an Fe-based metal of an &#x3b1;-&#x3b3; transforming component is subjected to hot rolling at a temperature of an A3 point or higher and is subjected to &#x3b1;-region rolling at a temperature of 300&#xb0; C. or higher and lower than the A3 point, and thereby a base metal sheet having a {100} texture in a surface layer portion is fabricated. Then, by performing a heat treatment under predetermined conditions, an Fe-based metal sheet is obtained in which a Z value is not less than 2.0 nor more than 200 when intensity ratios of respective {001}&#x3c;470&#x3e;, {116}&#x3c;6 12 1&#x3e;, and {223}&#x3c;692&#x3e; directions in a sheet plane by X-ray diffraction are set to A, B, and C respectively and Z=(A+0.97B)/0.98C is satisfied.

Fe-based metal sheet and manufacturing method thereof

On at least one surface of a base metal plate () of an &#x3b1;-&#x3b3; transforming Fe or Fe alloy, a metal layer () containing ferrite former is formed. Next, the base metal plate () and the metal layer () are heated to an A3 point of the Fe or the Fe alloy, whereby the ferrite former are diffused into the base metal plate () to form an alloy region () in a ferrite phase in which an accumulation degree of {200} planes is 25% or more and an accumulation degree of {222} planes is 40% or less. Next, the base metal plate () is heated to a temperature higher than the A3 point of the Fe or the Fe alloy, whereby the accumulation degree of the {200} planes is increased and the accumulation degree of the {222} planes is decreased while the alloy region () is maintained in the ferrite phase.
