PROBLEM TO BE SOLVED: To provide a blow molding mold with which a multi-space container can be manufactured. SOLUTION: The blow molding method for manufacturing the multi-space container is characterized in that it includes: a stage of assembling to form a plurality of molding spaces, by oppositely arranging open faces of each mold providing independent molding spaces inside, inserting a separation membrane into a support frame formed in the open face of each mold, and sealing the open face with the support frame; a stage of injecting preliminary moldings into the independent molding space of each mold and simultaneously or successively expanding and molding the respective preliminary moldings; and a stage of finishing by heat treating the projected part of the separation membrane.
