In a cutting tool, at least one of an upper contact part of an upper surface of a cutting insert and an upper jaw of a holder and a lower contact part of a lower surface of the cutting insert and a lower jaw of the holder includes a first concave-convex surface and a second concave-convex surface. A distance dbetween tops of first convex parts adjacent to each other among a plurality of first convex parts of the first concave-convex surface is smaller than a distance dbetween bottoms of second concave parts adjacent to each other among a plurality of second concave parts of the second concave-convex surface in a sectional view perpendicular to the longitudinal direction of the holder.
