An adhesive sheet to be bonded to a metal surface, which comprises an adhesive layer that is formed of an acrylic adhesive that uses a (meth)acrylic acid ester copolymer. The content of a (meth)acrylic acid alkoxyalkyl ester monomer (A) is 50% by mass or more and the content of a (meth)acrylic acid alkyl ester (B) having an acryl group with 1-4 carbon atoms is 5-45% by mass in the monomer components constituting the (meth)acrylic acid ester copolymer, while the content of a carboxyl group-containing monomer is 1% or less in the monomer components constituting the (meth)acrylic acid ester copolymer. Consequently, the adhesive sheet for metal surface bonding is capable of reducing white turbidity and metal corrosion under high temperature high humidity conditions. |
