Abstract:
1. A textured substrate for epitaxial film formation having a textured metal layer having a {100}<100> cube texture at least on one surface, comprising a crystal orientation improving layer made of a metal thin film of 1 to 5000 nm in thickness on said textured metal layer surface, wherein the crystal orientation improving layer is 20 nm or less in surface roughness (Ra), and wherein the crystal orientation improving layer is formed by epitaxial growth; wherein differences between orientation degrees (ΔΦ and Δω) in said textured metal layer surface and orientation degrees (ΔΦ and Δω) in said crystal orientation improving layer surface are both 0.1 to 3.0°, wherein both a plate width direction (TD) and rolling direction (RD) measurement of orientation degree Δω the have a difference of 0.1 to 3.0° between the textured metal layer surface and the crystal orientation improving layer surface.
