Polyester pressure-sensitive adhesive composition, polyester pressure-sensitive adhesive, pressure-sensitive adhesive sheet, decorative film, film for electronic member, and decorative molded object

A polyester adhesive composition comprising a polyester resin (A) and a polyepoxy compound (B), wherein

• the polyester resin (A) satisfies all of following (1) to (6):
• (1) the polyester resin (A) has structural units derived from a polyvalent carboxylic acid (a) and structural units derived from a polyhydric alcohol (b);
• (2) a content of structural units derived from a cyclic structure-containing polyvalent carboxylic acid (a1) relative to 100 mol % of the structural units derived from the polyvalent carboxylic acid (a) is 30 mol % or more;
• (3) the structural units derived from the polyhydric alcohol (b) include structural units derived from an aliphatic polyhydric alcohol (b1);
• (4) the polyester resin (A) has an acid value of 1.5 to 30 mg KOH/g;
• (5) the polyester resin (A) has a glass transition temperature of −75 to −20° C.;
• and
• (6) the polyester resin (A) has less than 140 mol % of structural units derived from a cyclic ester relative to 100 mol % of the structural units derived from the polyvalent carboxylic acid (a).
