Abstract
A metal foil for electromagnetic shielding, comprising: a metal foil base, an Sn—Ni alloy layer formed on one or both surfaces of the base, and an oxide layer formed on a surface of the Sn—Ni alloy layer, wherein the Sn—Ni alloy layer includes 20 to 80% by mass of Sn and has a thickness of 30 to 500 nm, and wherein when an analysis in a depth direction is carried out by an XPS being the depth from an outermost surface as X nm, and an atomic percentage (%) of Sn is represented by A(X), an atomic percentage (%) of Ni is represented by A(X), an atomic percentage (%) of oxygen is represented by A(X), and X is defined to be Xwhen A(X)=0, 30 nm=>X=>0.5 nm, and 0.4=>∫A(X)dx/∫A(X)dx=>0.05 in a section [0, X] is satisfied.
