Beschreibung
Zusammenfassung:	The present invention provides a sliding member which has a low coefficient of static friction with a mating member and is suitable for use in a reciprocating sliding portion. The sliding layer includes an island-shaped copper alloy phase dispersed in the sliding layer in the form of a sea-island structure surrounded by graphite, and the length in the direction parallel to the sliding surface with respect to the sliding layer is 25 To 500 [mu] m is set to be 5 to 40% by volume. As a result, the island-like copper alloy phase is taken in by the graphite at the time of startup loaded on the sliding layer, and slip occurs at the interface with the graphite, so that the island-shaped copper alloy phase has a slight elastic deformation And the coefficient of static friction with the mating member is lowered.
