In the multi-layer-coated member composed of an ultra-hard alloy substrate and a multi-layer coating formed thereon, the multi-layer coating comprises two or more first layers each composed of at least one of carbides, nitrides and carbonitrides of elements of Groups 4a, 5a and 6a of the Periodic Table and Al, and two or more second layers each composed of at least one of oxides, carboxides, oxinitrides and carboxinitrides of elements of Groups 4a, 5a and 6a of the Periodic Table and Al laminated alternately. The first layers adjacent via the second layer are continuous in crystal orientation. |
