摘要：PURPOSE:To enable production of a long-life electrode which is dense, has high adhesiveness and has decreases internal stress of electrodeposition by coating an underlying layer contg. Pt and Pd oxide, intermediate layer consisting of alpha-PbO2 and coating layer of beta-PbO2 contg. a fibrous material successively on a corrosion resistant metallic substrate. CONSTITUTION:A sheet, perforated sheet, etc., consisting of Ti, Zr, Nb, Ta, or the alloys thereof, etc., are used as the substrate and the sticking area is preferably increased by subjecting the surface thereof to a ruggedness forming treatment. The underlying layer contg. the Pt and/or Pd oxide for protecting the substrate and improving the adhesiveness to the intermediate layer is formed on the surface of such substrate. The intermediate layer consisting of the alpha-PbO2 to play mainly the role of connection is the formed thereon. Further, the beta-PbO2 coating layer contg. the granular or fibrous material which is electrochemically inert and has corrosion resistance is formed on the surface thereof. The effect of dispersing the internal stress of electrodeposition of the beta-PbO2 layer is obtd. by incorporating the above-mentioned granular or other material into the coating layer.
