PROBLEM TO BE SOLVED: To provide a polishing device for a bar-like body used for a magnetic head, capable of performing highly accurate polishing. SOLUTION: This polishing device for a bar-like body used for a magnetic head is constructed in such a manner that a bar-like body 22 having a magnetic head element part 22a and an ELG element part 22b formed is polished while monitoring the resistance value of the sensing part of the ELG element part 22b, and the strip height of the magnetic head element part 22a is adjusted, This device is provided with a holding means 20 for holding the bar-like body 22 with its first surface to be polished set down, and an actuator 30 for pressing the first surface of the bar-like body 22 to a lapping surface plate 32 by pressing a second surface opposite the polished surface of the bar-like body 22 held by the holding means 20 directly or via a flexible film 36.
