To provide a method of manufacturing a container that can achieve at a sufficiently high level both the reduction of plastic usage and the excellent light blocking property of the thin-wall container.SOLUTION: The container is a mold body by supercritical fluid molding, including: a bottom part with a first thin wall part of 0.3 to 0.6 mm in thickness; a side wall part with a second thin wall part of 0.25 to 0.4 mm in thickness; and a support part that extends from the base end provided along the peripheral part of the bottom part to the lower side. The leading end of the support part is positioned at the same level of the bottom face of the container or lower than the bottom face.SELECTED DRAWING: Figure 1 【課題】プラスチック使用量の削減と薄肉容器の優れた遮光性の両方を十分に高水準に達成可能な容器の製造方法を提供する。【解決手段】超臨界流体成形による成形体である容器であって、厚さ０．３～０．６ｍｍの第一の薄肉部を有する底部と、厚さ０．２５～０．４ｍｍの第二の薄肉部を有する側壁部と、底部の周縁部に沿って設けられた基端から下方に延びる支持部とを備え、支持部の先端は当該容器の底面と同じレベル又は底面よりも下方に位置する容器。【選択図】図１
