NEGATIVE ELECTRODE CURRENT COLLECTOR, NEGATIVE ELECTRODE USING THE SAME, AND NONAQUEOUS ELECTROLYTIC SECONDARY CELL

A negative electrode current collector for a non-aqueous electrolyte secondary battery comprising copper or a copper alloy, characterized in that the copper or copper alloy has a ratio I/Iof an intensity Iof a peak attributed to (200) plane to an intensity Iof a peak attributed to (111) plane, which satisfies the equation (1): 0.3 ≦ I 200 /I 111 ≦ 4.0 in an X-ray diffraction pattern measured using CuKα radiation as a radiation source.
