The present invention provides a slide member comprising: a first layer 2 mainly containing a first metal having thermal conductivity of 200 to 450 W/(mK) at room temperature to 450 K (177°C); a second layer 3 mainly containing a second metal having lower hardness than the first metal; and a third layer 4 provided between the first layer 2 and the second layer 3. The third layer 4 contains the first metal 5 as a parent phase and the second metal 6 as a secondary phase, an area ratio of the secondary phase in the third layer 4 being 10% to 30%, and a thickness of the third layer 4 being 3% or more of a total thickness of the third layer 4 and the first layer 2. There may also be a fourth layer 7 present between the second layer 3 and the third layer 4, the fourth layer including a fifth layer 8 and a sixth layer 9. The sixth layer 9 is composed of a group of minute intermetallic compound particles 10 and is distributed in a strip shape. |
