Abstract
The present invention is a laminated coating film such that at least one of each of the below mentioned coating film (Q) and coating film (R) are laminated in alternation on a substrate. [Coating film Q] At least one coating film selected from the group consisting of: a coating film having a compositional formula of TiBCNand satisfying the atom ratios of each element being 0.2≦a≦0.7, 0≦b≦0.35, and 0≦c≦0.35; a coating film having a compositional formula of SiCNand satisfying the atom ratios of each element being 0.2≦d≦0.50 and 0≦e≦0.3; and a coating film having a compositional formula of BCNand satisfying the atom ratios of each element being 0.03≦f≦0.25 and 0≦g≦0.5. [Coating film R] A coating film having a compositional formula of L(BCN) (where L is at least one element selected from the group consisting of W, Mo, and V) and satisfying the atom ratios of each element being 0≦x≦0.15 and 0≦y≦0.5.
