To provide a cutting tool capable of more increasing an agglutination preventing effect with excellent wear resistance, when cutting a metal material of high hardness.

This cutting tool is provided with a cutting base material 2 and a cutting edge tip 3 made of a cemented carbide material having higher wear than that of the cutting base material 2 and fixed to the cutting base material 2. In vicinities 31 and 32 of a portion in contact with at least a material to be cut of the cutting edge tip 3, hard protective films 4 including at least any one kind of Al-O system, Al-Ti-O system and Al-Zr-O system composite oxide, and carbide system and nitride system silicon compound are coated.
