PROBLEM TO BE SOLVED: To stably continue the electrolysis of an electrolyte containing impurities using an electrode having high strength and high toughness. SOLUTION: A three-dimensional electrode 15 fabricated by bending a plurality of snicks 12 which are formed in a plate-like metal electrode substrate 11 toward the same direction to form an elastic conductive body 13 is used for the electrolysis of the electrolyte containing the impurities such as the electrolysis of white liquor. The three-dimensional electrode with higher strength and higher toughness is provided only by bending the plurality of the formed snicks. When the three-dimensional electrode is used in an ion exchange membrane electrolytic cell, the positional relation among mutual members is made stable, thus polysulfide ion or the like can be produced at high efficiency without mechanically damaging an ion exchange membrane or the like and without excessively deforming the same nor making power supply insufficient. Since the electrode has a wide surface area, the impurities deposited per unit surface area is made small to continue the electrolysis over a long period. COPYRIGHT: (C)2008,JPO&INPIT
