Claim 10:
11. A sliding member comprising a laminate at a sliding portion, the laminate comprising
a base substrate; and
a coating layer formed on the base substrate;

the hard particle portions are derived from hard particles;
the portions bond with each other via an interface;
each of the hard particle portions has a non-spherical shape;
an aspect ratio of the hard particle portions is 1.3 or more in a median value, and
the coating layer contains a precipitation phase at least in a part of an interface between the copper alloy particles, or at least in a part of a vicinity of an interface of the copper alloy particles adjacent to the hard particles.
