A hard laminated film wherein a layer A and a layer B having specific compositions are deposited alternately so that the compositions of layer A and layer B are different. The thickness of layer A per layer is twice or more the thickness of layer B per layer, the thickness of layer B per layer is 0.5 nm or more, and the thickness of layer A per layer is 200 nm or less. Layer A has a cubic rock-salt
crystal structure such as that of Ti, Cr, Al, V
nitride, carbonitride or
carbide, and layer B is a hard film having a
crystal structure other than cubic such as that of BN, BCN, SiN, SiC, SiCN, B—C, Cu, CuN, CuCN or metallic Cu. Alternatively, layer A has a
chemical composition satisfying the following formula (1), and layer B has a
chemical composition satisfying the following formula (2). Layer A: Cr(BaCbN1-a-b-cOc) 0≦a≦0.15, 0≦b≦0.3, 0≦c≦0.1, 0.2≦e≦1.1 (1) Layer B: B1-s-tCsNt 0≦s 0.25, (1−s−t) / t≦1.5 (2) Alternatively, Layer A has a specific
atomic ratio composition of (Ti1-x-yAlxMy)(BaCbN1-a-b-cOc) and Layer B has one or more specific
atomic ratio compositions selected from among the compositions B1-x-yCxNy, Si1-x-yCxNy, C1-xNx, Cu1-y(CxN1-x)y. Alternatively, Layer A has one of the following Compositional Formulae 1 or 2. Formula 1: (Ti1-x-yAlxMy), (BaCbN1-a-b-cOc), Formula 2: (Cr1-αXα)(BaCbN1-a-b-cOc)e (X is one or more
metal elements selected from among Ti, Zr, Hf, V, Nb, Ta, Mo, W, Al, Si. Layer B has the following compositional formula 3. Formula 3 M(BaCbN1-a-b-cOc). M is one or more
