Claim:
A hard-coated material, comprising: a substrate; and a hard-coating film on the substrate; wherein the hard-coating film, comprises: at least two lamination units in laminated structure formation, wherein a lamination unit comprises, laminated alternately in succession: a lower layer-A; and an upper layer-B; wherein a first lower layer A is on the substrate, and each layer-A has a component composition of formula: Ti v M 1-v (C x N y O z ), wherein M is at least one specie selected from the group consisting of Group-4 elements, Group-5 elements, Group-6 elements, Si, Al, B, and Y, excluding Ti; 0.6≦v≦1 0≦z≦0.1 x+y+z=1; each layer-B has a component composition of formula: Ti v Cr w M 1-v-w (C x N y O z ), wherein M is at least one specie selected from the group consisting of Group-4 elements, Group-5 elements, Group-6 elements, Si, Al, B, and Y, excluding Ti and Cr; 0≦v≦0.6 0.05<w v+w≦1 0≦x≦0.5 0≦z≦0.1 x+y+z=1; wherein a thickness ratio of a layer-B to a layer-A is at least 2; and a thickness of a layer-A is within the range of 0.1 to 3 μm both inclusive, a thickness of layer-B is within the range of 1 to 10 μm both inclusive, and a total thickness of a plurality of layers-B is at least 5 μm.
