Abstract: A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.
