A cutting tool includes: a cutting edge configured on an intersecting line of a rake surface and a flank; a breaker wall formed inside the cutting edge and protruding above the cutting tool; a boss part including a boss surface formed above the breaker wall; and a plurality of recessed parts formed in the boss part so as to extend toward the cutting edge. The width of the breaker wall in a direction in which the cutting edge extends along an intersecting line (including a virtual intersecting line or a virtual extension of the intersecting line) of the boss surface and the breaker wall, is greater than the width of a groove formed by the recessed part along the same intersecting line.
