Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polybutylene terephthalate having improved quality by which, when terephthalic acid containing acetic acid, and 1,4-butanediol are used as raw materials, and an esterification reaction and a polycondensation reaction following the reaction are carried out, the retardation of the polycondensation can be extremely reduced to carry out the polycondensation reaction smoothly, and the 1,4-butanediol distilled off at the polycondensation reaction can be effectively recovered and utilized in the esterification step as it is. SOLUTION: This method for producing the polybutylene terephthalate by subjecting the terephthalic acid containing the acetic acid and the 1,4-butanediol to the esterification reaction, and further subjecting the reaction product to the polycondensation reaction is characterized in that an alkaline compound is added to the reaction mixture at an arbitrary step before finishing the polycondensation reaction.
