an overlay formed with an alloy plated film consisting essentially of Bi and Sb, wherein

the Sb concentration in the overlay increases as the depth from the surface of the overlay increases, and

the absolute value of the gradient of Sb concentration in a first region from a first depth from the surface of the overlay to a second depth from the surface of the overlay is greater than the absolute value of the gradient of Sb concentration in a second region from the surface of the overlay to the second depth from the surface of the overlay, the second depth is less than the first depth.
