A diamond-coated hard material having a diamond- or diamond-like carbon coated layer with a high bonding strength to a substrate is provided. The coated hard material comprising a diamond- and/or diamond-like carbon-coating layer formed on the surface of a hard material, i.e. substrate is character- ized in that (I) (1) microscopic roughness is present on the surface of the sub- strate and (2) protrusive parts thereof are defined by the surface roughness Rmax within a range of 1.0 to 30 µ m in a standard length when the standard length is 50 µ m in the interface of the diamond- and/or diamond-like carbon coated layer and the substrate, and (II) (1) microscopic roughness is present on the surface of the substrate, (2) at least one protrusive part is present in a standard length when the standard length is 10 µ m in the interface of the diamond- and/or diamond-like carbon coated layer and the substrate, (3) the ratio of sum A of the lengths of dent parts to sum B of the lengths of the pro- trusions is in the rangeof 0.05 <= A/B <= 20 in the standard length in the interface and (4) the protrusive parts are intruded into the diamond-coated layer.
