PURPOSE:To provide a low-cost corrosion-resistant tape which is easy to apply and has an excellent corrosion preventive effect, prepd. by applying an electrically conductive adhesive to the back side of a tape or a strip consisting of a material which is electrochemically baser than a metal object to be finished, with some areas left uncoated. CONSTITUTION:An adhesive 2 is applied to the back side of a tape or a strip 1 consisting of a metal which is electrochemically baser than a metal object to be finished (e.g. Zn, Al or Mg when the metal material is made of iron or steel) with areas 3 left uncoated. The tape may be backed with a protective layer 4 such as silicone-finished paper or discharge-finished polyethylene resin film and may be wound up into a roll. For application, a proper length of the tape is drawn from the roll and cut with scissors, etc. and the cut piece is wound round an object followed by soft pressing.
