Abstract (en)
Disclosed is a surface treatment apparatus including one of a positive electrode member and a negative electrode member to be electrically connected to a treatment-object article made of metal and having an annular treatment-object area in an outer circumferential face thereof, a frame member having a non-conductive inner circumferential face opposed with a gap to the outer circumferential face and to the annular treatment-object area, a non-conductive elastic seal member capable of forming an electrolysis solution path along the annular treatment-object area by sealing the gaps between portions of the outer circumferential face opposed to each other across the annular treatment-object area and the inner circumferential face, the other one of the positive electrode member and the negative electrode member having a bar-like shape with a leading end portion that protrudes into the electrolysis solution path toward the treatment-object article, and an electrolysis solution circulating means for circulating an amount of electrolysis solution along the electrolysis solution path.
