Claim Text:
1. An Fe-based metal sheet, comprising: less than 0.2 mass % C and having a composition that is capable of causing an α-γ transformation, wherein a ferrite-forming element, being one element or more selected from the group consisting of Al, Mo, Ga, Sn, Ti, Ge, Sb, V, W, Zn and As is alloyed on a partial or whole region of the Fe-based metal sheet, and when intensity ratios of respective {001}<470>, {116}<6 12 1>, and {223}<692>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, a Z value is not less than 2.0 nor more than 200; wherein at least a partial region including surfaces of the Fe-based metal sheet is an α single phase region that is alloyed with said ferrite-forming element, and a ratio of the α single phase region to a cross section of the Fe-based metal sheet is 1% or more, wherein an accumulation degree of {200} planes is not less than 30% nor more than 99%, and an accumulation degree of {222} planes is not less than 0.01% nor more than 30%, and said accumulation degree of {200} planes is expressed by Expression (1) below and said accumulation degree of {222} planes is expressed by Expression (2) below, wherein i (hkl) is an actually measured integrated intensity of {hkl} planes in the surface of the Fe-based metal sheet, and I (hkl) is a theoretical intergrated intensity of the {hkl} planes in a sample having a random orientation, and 11 kinds of planes of {110}, {200}, {211}, {310}, {222}, {321}, {411}, {420}, {332}, {521}, and {442} are used as the {hkl} planes.
