A metal foil for a current collector of a secondary battery formed by electrodeposition and has a thickness (T) of 8 to 40 &#x3bc;m, the metal foil satisfying the following formulae:4.9&#xd7;10&#x2266;31&#xd7;104.5&#x2266;&#x3b5;&#x2212;(0.0005&#xd7;)&#x2266;15where S is a breaking strength (MPa), &#x3b5; is a tensile elongation (%) and Y is a Young's modulus (MPa). This foil is preferably a nickel foil and is manufactured by softening or annealing the metal foil obtained by electrodeposition. Thereby, a metal foil for a negative electrode of a secondary battery is obtained with an excellent capability of supporting the active material and large electric conductivity.
