摘要： A throw-away tip 1 of the present invention has a rake face 5 formed on a surface of a base 2 and a flank 8 intersecting with the rake face 5. The intersection ridge between the rake face 5 and flank 8 defines a cutting edge 9. A sensor line 12 is made out of a conductive film extending along the cutting edge 9 and having a predetermined width. The sensor line 12 is provided in an electrically insulative relation with respect to the base 2. According to the present invention, one side edge L of the sensor line 12 is provided on the flank 8 substantially in parallel with the intersection ridge, while the other side edge U of the sensor line 12 is provided on the rake face 5 side from the intersection ridge.
