To provide the subject member hard to fall, having sufficient densiness of the metallic structure and excellent in wear resistance by composing it of a specified volume % of cubic boron nitride particles, and the balance cemented carbide or cermet and providing it with a coating layer composed of a metal selected from the group VIa elements, Re, or the like, an alloy composed of elements such as the group IVa and Va elements, carbides, or the like.

This member contains 3 to 50 vol.% cubic boron nitride particles and has one or more coating layers of a metal selected from the group VIa elements in the Periodic Table, Re, Os, or the like, an alloy consisting of two or more kinds of elements among the group IVa, Va and VIa elements in the Periodic Table, Al and Si and a compd. of the carbides, nitrides, oxides, or the like, of the group IVa, Va and VIa elements in the Periodic Table, Al and Si or the solid solutions thereof, or the like. The m.p. of this coating layer is ≥1300°C, the average particle diameter D of the cubic boron nitride particles is 0.1 to 100 μm, and in the case the thickness of the coating layer is defined as (d), k, i.e., the value of ((0.5D+d)/0.5D)3 is 1.002 to 1.5.
