Abstract
A sliding member of the present embodiment includes: a lining layer including a Bi phase; and a coating layer containing Ni, the coating layer being provided on a surface of the lining layer, the coating layer partially forming an entrance portion that has entered the lining layer side at an interface with respect to the lining layer. At any observation region including the interface between the lining layer and the coating layer, a value R=S1/S2 of a ratio of a maximum area S1 of the Bi phase included in the lining layer to a maximum area S2 of the entrance portion that has entered the lining layer is 1.00≤R≤9.00.
