A cutting toolincludes a cutting edge, a rake faceand a flankand is used for cutting a surface of a cylindrical or columnar work W by a skiving process. The cutting toolis configured to satisfy a relational expression:tan(cos &#x3b2;/cos(&#x3b1;&#x2212;&#x3b2;)&#xd7;tan(cos())&#x3c;&#x3c6;&#x2264;90&#xb0;where '&#x3c6;' denotes a rake angle, '&#x3b1;' denotes an inclination angle of the cutting edgewith respect to the rotation axis A, &#x201c;&#x3b2;&#x201d; denotes an angle between a feed direction of the cutting tooland a direction orthogonal to a rotation axis A in a plane view of the cutting tooland the work W, &#x201c;r&#x201d; denotes a radius of an outer circumferential surface of the work W before processing, and &#x201c;r'&#x201d; denotes the radius of the outer circumferential surface of the work W after processing.
