Zusammenfassung:	A rolled copper foil comprises one of copper and a copper alloy. The rolled copper foil has a rolled surface and two side surfaces adjacent to the rolled surface. Each of the side surfaces being a non-sheared surface that is not a sheared surface. An area ratio of crystal grains oriented at a deviation angle of less than or equal to 13° from Cube orientation is greater than or equal to 6%.
