Abstract
A coating for a conductor, the coating having a layered structure of a palladium layer. The palladium layer has a crystal plane whose orientation rate is 65% or more, which means 65% or more of the crystal planes of the palladium layer are aligned to this crystal plane. Preferably the crystal plane whose orientation rate is 65% or more in the coating is the (111) plane or (200) plane.
