Abstract: A metal member is manufactured that has a plating layer of precious metal on the surface of a bare metal portion formed of a predetermined metal. First, a surface layer of the bare metal portion is removed. Then, a plating of precious metal is applied to the portion where the surface layer of the bare metal portion was removed. Then, the metal member is heat treated in an inert atmosphere. As a result, a metal member can be manufactured that has less carbide and hydrogen near a boundary surface of the plating layer and the bare metal portion than it would if the removing step and the heat treating step were not performed. With a metal member manufactured in this way, the plating layer does not easily peel away.

The present invention is a textured substrate for epitaxial film formation, including a crystal orientation improving layer made of a metal thin film of 1 to 5000 nm in thickness on the surface of the textured substrate for epitaxial film formation having a textured metal layer at least on one surface, wherein differences between orientation degrees (?? and ??) in the textured metal layer surface and orientation degrees (?? and ??) in the crystal orientation improving layer surface are both 0.1 to 3.0°. Further, when another metal different from the metal constituting this textured substrate crystal orientation improving layer is added equivalent to a thin film which is 30 nm or less, and subsequently is subjected to heat treatment, the smoothness of that surface can be improved.
