PROBLEM TO BE SOLVED: To provide a polyester direct blow molded article which can be molded at a low processing temperature, can lower a production cost, and is excellent in moldability and heat resistance. SOLUTION: Provided is a polyester direct blow molded article characterized by molding a polyester resin which comprises a dicarboxylic acid component consisting mainly of terephthalic acid and a diol component containing 1,6-hexanediol in an amount of≥50 mol%, has a melting point of 100 to 150°C, and contains a crystal-nucleating agent in an amount of 0.01 to 5.0 mass%, and in which a DSC curve exhibiting a temperature-falling crystallization determined by DSC satisfies an expression (1): b/a≥0.05 (mW/mg×°C).
