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=S/Sof a ratio of a maximum area Sof the Bi phase included in the lining layer to a maximum area Sof the entrance portion that has entered the lining layer is 1.00≤R≤9.00.

Sliding member

A multi-layer slide member has a back metal layer mainly composed of a steel plate and a porous layer having a metallic porous member and a resin composition filled in the metallic porous member. The metallic porous member has granular portions and narrow portions and includes a structure, in which the granular portions are connected with each other through the narrow portion. Parts or the entirety of the narrow portions have a Bi phase and a Sn&#x2014;Ni&#x2014;Cu intermetallic compound phase.
