A method for manufacturing a glass container and an apparatus therefor capable of providing the container by pressing of a glass substrate using a die while keeping the glass substrate uniformly heated and softened. The glass substrate is heated while being kept lifted from a lower mold of a forming die and then subject to integral forming by the forming die. This permits the glass substrate to be integrally formed into the glass container in the form of a finished product, resulting in the number of steps and time required for processing being reduced.
