Abstract
Provided is a multilayer hard film capable of elongating a lifetime of a member. A multilayer hard film () is formed by alternately stacking a layer A () made of TiSi(BCN) [where 0.05≦x≦0.4, p≧0, q≧0, r>0, p+q+r=1], and a layer B () made of at least one selected from the group of TiBCN[where 0.05≦a≦0.5, 0.25≦b≦0.6, 0≦g≦0.5], SiCN[where 0.2≦c≦0.5, 0.25≦d≦0.5], BCN[where 0.03≦e≦0.25, 0.3≦f≦0.55], TiB, SiC and BC, one another over the surface of the substrate ().
