A sliding member has a coating layer deposited on a base material through
an intermediate layer, wherein the intermediate layer is formed of a
lead-free metal, and the coating layer is formed of Bi or a lead-free Bi
alloy; and wherein a grain in the intermediate layer becomes gradually
large toward a coating layer side from a base material side, and a grain
in the coating layer forms a columnar grain of which the major axis
directs toward the surface of the coating layer from the intermediate
layer side. Thus formed configuration improves a bonding strength between
the base material and the coating layer owing to the intermediate layer,
and has the grain of the coating layer formed into a desirable shape for
bearing a load from an opposite material to improve fatigue resistance.
