Metal foil excellent in electrical contact stability |
摘要 |
The present invention provides a metal foil excellent in electrical contact stability, and low in cost, by eliminating plating processes. Specifically, the present invention is a metal foil excellent in electrical contact stability characterized by having a surface roughness wherein the ratio Ra/Sm between the arithmetic average of roughness Ra and the average interval Sm of concavities and convexities is 0.001 or more, which average values are obtained by measuring the roughness in the direction in which the average interval Sm of the concavities and convexities on the surface is smallest. It is preferable that the material of the metal foil is stainless steel or phosphor bronze.
