Abstract
A laminate includes a base substrate, and a coating layer formed on the base substrate. The coating layer includes a copper alloy portions derived from precipitation-hardening copper alloy particles and hard particle portions which are harder than the copper alloy portions, the hard particle portions are derived from hard particles, and the parts bond with each other via an interface. Each of the hard particle portions has a non-spherical shape. A sliding member includes the laminate in at least one sliding portion. A method for manufacturing a laminate includes a step of spraying a mixture in a non-molten state including precipitation-hardening copper alloy particles and hard particles having a non-spherical shape and being harder than the copper alloy particles onto a base substrate, to form a coating layer on the base substrate.
