Zusammenfassung:PROBLEM TO BE SOLVED: To provide a carbide tool excellent in a tool life.SOLUTION: A carbide tool 1 comprises a base material 2 and a hard protective film 3. The hard protective film 3 is formed on a surface of the base material 2 and includes a surface 31 with a texture. The hard protective film 3 includes at least one kind of material selected from a group of a metal nitride, a metal carbide, and a metal carbonitride, and a metal oxide. The texture includes a plurality of recesses 5 arranged in a matrix shape in which an opening diameter of the recess 5 is 0.05-0.50 μm, a depth of the recess 5 is 0.10-0.30 μm, and an interval between adjacent recesses 5 is 10-100 μm.SELECTED DRAWING: Figure 1 【課題】優れた工具寿命を有する超硬工具を提供する。【解決手段】本実施形態による超硬工具１は、基材２と、硬質保護膜３とを備える。硬質保護膜３は、基材２の表面上に形成されており、テキスチャーを含む表面３１を有する。硬質保護膜３は、金属窒化物、金属炭化物、金属炭窒化物及び金属酸化物からなる群から選択される少なくとも１種を含有する。テキスチャーは、マトリクス状に配置された複数の凹み５を含む。凹み５の開口径は０．０５〜０．５０μｍであり、凹み５の深さは０．１０〜０．３０μｍであり、隣り合う凹み５同士の間隔は１０〜１００μｍである。【選択図】図１
