The aqueous dispersion adhesive composition contains an aqueous dispersion copolymer obtained by reacting of a reaction component containing alkyl (meth)acrylate whose linear or branched alkyl group has 4 to 18 carbon atoms, (meth)acrylic acid, a phosphoric acid group-containing vinyl monomer and an alkoxysilyl group-containing vinyl monomer to react; and a crosslinking agent having reactivity with a carboxyl group. In the aqueous dispersion adhesive composition, an amount of the crosslinking agent is from 0.07 to 4 parts by weight per 100 parts by weight of the aqueous dispersion copolymer, and in an adhesive layer made of the aqueous dispersion adhesive composition, an elongation at 90° C. is 200% or less.
