A fine flaky copper powder having an average major axis diameter of 4 to 10 &mgr;m and a flakiness of 2 to 20, has a bulk density of 2 to 4 g/cm3 and a BET specific surface area of 0.4 to 1.5 m2/g; A process for producing the copper powder includes introducing a copper slurry into a medium type agitation mill and flattening the powder.
