Abstract:
    An electrode structure is constituted by a first electrode, and at least one second electrode providing a pair of opposite portions with a prescribed spacing therebetween at which the first electrode is disposed. The electrode structure is suitably used for electrolytic etching and is effective in providing an accurate etching pattern without damaging the surface of an etching object.
