PROBLEM TO BE SOLVED: To provide a contact detection device for a machine tool suitable for a system to sense contact of a measuring probe with a work processed while the spindle is rotated for rotating the probe. SOLUTION: The probe 26 of this contacting detection device is attached to a holder 21, while the probe 26 is held being insulated by a sleeve 25 from the body of the holder 21, and an electric conductive collar 22 to feed current to the probe 26 is insulated from the body 21 fitted by an insulating collar 23. A current feeding brush 35 advances and retreats relative to the electric conductive collar 22, and a current feeding brush 33 is put in slide contact with the collar 22 so as to feed the current to the probe 26 rotating.
