The present invention provides a textured substrate for forming an epitaxial film, including a textured metal layer on at least one surface of the layer, the textured metal layer including a copper layer having a cube texture, the textured metal layer having, on a surface of the layer, palladium added in an amount of 10 to 300 ng/mmper unit area, the hydrogen content of the surface of the textured metal layer being 700 to 2000 ppm. This textured substrate is produced through a step of adding 10 to 300 ng/mmper unit area of palladium by strike plating to a surface of the copper layer having a cube texture.
