According to the present invention, a pressure-sensitive adhesive for a motor vehicle brake disc antirust film, which comprises an acrylic resin based pressure-sensitive adhesive prepared by crosslinking an acrylic copolymer containing a unit based on a (meth)acrylamide based monomer and having a weight average molecular weight of 500,000 to 1,100,000 with a polyisocyanate compound by the utilization of the unit based on a (meth)acrylamide based monomer as a crosslinking base point. The pressure-sensitive adhesive for a motor vehicle brake disc antirust film can provide a motor vehicle brake disc antirust film which is hardly peeled off when adhered onto a motor vehicle wheel.
