Provided is a container manufacturing method of manufacturing a resin container, the method including: a preform feed step (S1) of feeding a preform (1) into a cavity (3) of a batch-type mold for blow molding (2), the preform (1) being formed into a bottomed tubular shape by a resin material; a liquid blow step (S2) of filling a pressurized liquid into a preform (1) disposed in the cavity (3); and an ejection step (S6) of ejecting a container (4) after blow molding from the cavity (3). The method further includes a mold slide step (S3) of sliding the mold for blow molding (2) to a slide position (6) that is different from a position (5) of the mold for blow molding (2) in the liquid blow step (S2).
