PROBLEM TO BE SOLVED: To provide a rolled copper foil, a surface-treated copper foil and a laminate plate which satisfactorily adhere to a resin, and in which the resin after the copper foil has been removed by etching has excellent transparency.SOLUTION: A rolled copper foil is tough pitch copper based on JIS H3100 C1100 or oxygen-free copper based on JIS-C1020. An average value between a mirror reflectance at an incident angle of 20° in a direction parallel to rolling and a mirror reflectance at an incident angle of 20° in a direction perpendicular to rolling is 30 or more. |
