<P>PROBLEM TO BE SOLVED: To provide a sliding member farther superior in fatigue resistance and seizure resistance. <P>SOLUTION: The sliding member has a third layer 4 disposed between a first layer 2 which mainly comprises a first metal of which thermal conductivity ranges from 200 to 450 W/(mK) in a range between 450K and a room temperature, and the second layer 3 which mainly comprises a second metal whose hardness is lower than the first metal. The third layer 4 has the first metal as a parent phase and the second metal as a secondary phase, and area rate of the secondary phase in the third layer ranges from 10 to 30%, and thickness of the third layer amounts to 3% or more of the total thickness of the third layer and the first layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
