Abstract: A liquid blow molding device for liquid blow molding a resin preform into a container having a predetermined shape. The liquid blow molding device includes a mold in which the preform is disposed; a stretch rod that axially stretches the preform disposed in the mold (; and a pressurized liquid supply that supplies a pressurized liquid to the preform. The liquid blow molding device operates such that the amount of the liquid supplied from the pressurized liquid supply to the inside of the preform before completing the stretching of the preform by the stretch rod (22) is 50% or less of the amount of the liquid to be filled in the container after the completion of the liquid blow molding.
