Abstract
The invention relates to an adhesive composition, an adhesive, an adhesive sheet and a double-sided adhesive sheet. Provided is an adhesive composition which uses a recycled material that is environmentally friendly to the earth, has good adhesive properties with respect to various adherends, and has excellent adhesive properties such as adhesive force and holding power, and which is a polyester resin composition containing a polyester resin (A), the polyester resin (A) contains a structural unit derived from at least one compound (a1) selected from a dimer acid and a dimer glycol, and a structural unit derived from an aromatic compound (a2), and the ratio (X1 / X2) of the molar concentration (X1) of the structural unit derived from the compound (a1) to the molar concentration (X2) of the structural unit derived from the aromatic compound (a2) is greater than 1.0.
