Title:
METAL FOIL FOR ELECTROMAGNETIC WAVE SHIELDING, ELECTROMAGNETIC WAVE SHIELDING MEMBER, AND SHIELDED CABLE
Document Type and Number:
WIPO Patent Application WO/2015/181970
Kind Code:
A1
Abstract:
[Problem] To provide: a metal foil that is for electromagnetic wave shielding and resists a decrease in corrosion resistance even when exposed to high-temperature environments; an electromagnetic wave shielding member, and a shielded cable. [Solution] The metal foil (10) for electromagnetic wave shielding is such that an underlayer (2) comprising Ni is formed at one or both sides of a substrate comprising a metal foil (1), an Sn-Ni alloy layer (3) is formed at the surface of the underlayer, the Sn-Ni alloy layer contains 20-80 mass% of Sn, and when the total adhered quantity of Sn is TSn (μg/dm2), the fraction of Sn in the Sn-Ni alloy is ASn (mass%), the total adhered quantity of Ni is TNi (μg/dm2), and the fraction of Ni in the Sn-Ni alloy is ANi (mass%), TSn is 500-91,000 μg/dm2, TNi is 2200-236,000 μg/dm2, and 170,000 ≥ {TNi - TSn × (ANi/ASn)} ≥ 1700.
