Adhesive tape

An adhesive tape comprising:

• a substrate [I];
• and
• an adhesive agent layer of a polyester adhesive agent provided on at least one of opposite surfaces of the substrate [I];
• wherein the substrate [I] is one selected from the group consisting of a polyolefin resin foam substrate, a urethane resin foam substrate, and an acrylic resin foam substrate;
• wherein the polyolefin resin foam substrate has an apparent density of 10 to 200 kg/m3;
• wherein the urethane resin foam substrate and the acrylic resin foam substrate have an apparent density of 200 to 1000 kg/m3;
• wherein the polyester adhesive agent is made from a polyester adhesive agent composition [II] which comprises a polyester resin (A)
• having a weight average molecular weight of 20,000 to 300,000, and having
• a structural unit derived from a polyol and
• a structural unit derived from
• a polyvalent carboxylic acid compound containing an aromatic structure-containing compound in a proportion of not greater than 40 mol % of the polyvalent carboxylic acid compound;
• wherein the polyester resin (A) has a structural unit derived from a hydrogenated polybutadiene structure-containing compound (a3);
• wherein the structural unit derived from the hydrogenated polybutadiene structure-containing compound (a3) is present in a proportion of less than 10 wt. % with respect to 100 wt. % of the polyester resin (A),
• wherein the polyester resin (A) has an acid value of not greater than 3 mg KOH/g, and
• wherein the polyester resin (A) has an ester bond concentration of 7 to 9.5 mmol/g.
