Abstract:
A material for electric sliding contact comprising, on a conductive substrate, a first layer composed of a noble metal or an alloy comprising the noble metal as a major component with an arithmetic average roughness Ra of (A) μm and, as an upper layer of the first layer, a second layer composed of a noble metal or an alloy comprising the noble metal as a major component with a covering thickness of from 0.001×(A) μm or more to (A) μm or less, wherein the noble metal forming the second layer or the noble metal as a major component of the alloy forming the second layer is a different element from the noble metal forming the first layer or the noble metal as a major component of the alloy forming the first layer.
