Abstract

The pressure-sensitive adhesive tape of the present invention is a pressure-sensitive adhesive tape comprising a pressure-sensitive adhesive layer comprising a photo-cured acrylic resin, a metal having a lower potential than that of iron, and an electroconductive material, wherein the pressure-sensitive adhesive layer has a total light transmittance X, per micrometer of the thickness, of 99.85% or less, and the pressure-sensitive adhesive layer has a total light transmittance Y of 6% or more. The present invention can provide a pressure-sensitive adhesive tape having a great adhesive force on both the front side and the back side and having good sacrificial corrosion resistance.
