Provided is an adhesive that uses plant-derived, environmentally friendly raw materials, obtained by crosslinking an adhesive composition containing a polyester resin (i) having a structural unit derived from a polycarboxylic acid (a) and a structural unit derived from a polyol component (b) as an adhesive having good adhesive properties and excellent dent resistance and transparency, wherein the polyester resin (i) contains 60 wt% or more relative to the polyester resin (i) of a structural unit derived from at least one selected from the group consisting of dimer acids, sebacic acids, and dimer diols and contains a glycol (b1) having an even number of carbon atoms (however, excluding dimer diols) as the polyol component (b), the ester group concentration of the polyester resin (i) is 2 mmol/g or higher, and the adhesive has an adhesive force (α) of 1 N/25 mm or higher under specific conditions. |
