To easily manufacture a composite container configured by combining an inner plastic container and an outer paper container.
An outer container (2) having a notch (7) at a predetermined place, and a heated inner container preform (1a) are loaded in the mold (10) of the inner container. Then, by blow-molding the preform into the inner container, the inner container is closely stuck to the inner surface of the outer container, and simultaneously a bulged part to project into the notch is formed in the inner container. The molding of the inner container and the integration of the inner container and the outer container are simultaneously completed. Thus, the manufacturing process of the composite container is simplified and quickened, thereby achieving low manufacturing costs.
