Abstract: The purpose of the present invention is to further level the amount of polishing during electrolytic polishing of the inside of a hollow pipe. A holding frame for vertically holding a hollow pipe is pivotally supported on a rack so as to be vertically invertible about the vertical center of the hollow pipe. An electrode is inserted through the hollow pipe and a liquid buffer is disposed on each end of the hollow pipe. A valve mechanism is capable of switching a liquid supply/discharge circuit so as to supply an electrolyte via the liquid buffer positioned at the bottom and discharge the electrolyte via the liquid buffer positioned at the top whether it is before or after the inversion of the holding frame (inversion of the hollow pipe). During an electrolyte supply period before and after the inversion, an electrolytic treatment is as a matter of course carried out for a predetermined length of time. Although said switching by the valve mechanism may be manually performed, a control means may also be used.
