    摘要: A cutting tool including a base, a TiN layer on the base, a TiCN layer on the TiN layer, and an Al2O3 layer on the TiCN layer. The base contains a cemented carbide. The TiN layer and the TiCN layer contain Nb. A Nb content in the TiCN layer at a middle portion of the TiCN layer in a thickness direction is 0.1% by mass or more, and the Nb content in the Al2O3 layer at a middle portion of the Al2O3 layer in the thickness direction is 0.05% by mass or less.
