There is provided a copper-based sliding alloy excellent in wear resistance and anti-seizure property. A phase of 2 to 30 wt. % lead is dispersed in the copper alloy. This lead phase contains 0.1 to 6 vol. % hard particles such as SiC, SiO,, Si,N,, Al,O,, TiC, WC and TiN having an average particle size of 5 to 25 &mgr;m. Because hard particles are included in the lead phase, wear resistance is excellent and anti-seizure property is improved. The lead phase, which is soft, serves as a cushion and the attack on a mating member by hard particles is reduced. Further, the falling-off of lead is minimized because the lead phase also includes the hard particles.
