<P>PROBLEM TO BE SOLVED: To provide a copper foil for a flexible printed wiring board, a manufacturing method of the same, and a flexible printed wiring board, capable of preventing a skirt-like pattern profile in an etching process of CCL from occurring, and forming a circuit having a uniform circuit width. <P>SOLUTION: The copper foil for a flexible printed wiring board is applied with a nickel - cobalt alloy plating layer on a glossy face side of a copper foil. The ratio of an area occupied by a crystal grain having a (011) plane orientation of the nickel - cobalt alloy plating layer is 80% or higher. <P>COPYRIGHT: (C)2013,JPO&INPIT |
