    摘要： A cutter (1) includes a rake face (2a) on which a recessed groove (2d) extending along a direction of a rotation axis (C1) of a rotary holder (5) to be open at a flank face (2b) of the cutter (1) are formed. The recessed groove (2d) includes a plurality of recessed grooves (2d) formed at predetermined intervals along a direction intersecting with the rotation axis (C1). A cutting blade portion (2e) extending along a direction intersecting with the rotation axis (C1) is provided on a continuous portion of the rake face (2a) and the flank face (2b). The cutting blade portion (2e) includes a first region (2f) made up of an intersecting portion of the rake face (2a) and the flank face (2b) and a second region (2g) made up of a peripheral edge portion of an opening portion of the recessed groove (2d) at the flank face (2b).
