摘要： An adhesive is provided that has superior bonding strength and that can be beneficially used as a structural adhesive and, when formed into a sheet shape, has superior shape retention. The adhesive includes an acrylic polymer; an epoxy resin in an amount of 80 to 300 parts by mass per 100 parts by mass of the acrylic polymer; at least one type of thermoplastic resin selected from the group consisting of a phenoxy resin and a polyvinyl butyral resin, in an amount of 15 parts by mass or greater per 100 parts by mass of the acrylic polymer; and an epoxy resin curing agent. In such an adhesive, the acrylic polymer is a polymer of monomer components including a (meth)acrylic acid ester having a homopolymer Tg of 80° C. or higher, a nitrogen-containing monomer, and a crosslinking monomer having an epoxy group.
