To provide a self-standing packaging container which has the self- standing property even when a slender commodity such as a plastic bottle is stored and has the display effect.

An inner peripheral wall 11 is formed on the whole periphery except one side close to a folding part 15 at a center of one transparent plastic sheet 10, and a lid part 14 is formed inside the inner peripheral wall having an outwardly-swollen sub commodity storage part with the inclination larger toward a free end 12 from substantially the center. A peripheral wall 22 which is fitted to the lid part in an attachable/detachable manner with an outer peripheral wall 21 inclined corresponding to the inner peripheral wall 11 is protruded over the whole periphery except one side close to the folding part 15, and a container body part 25 having an outwardly-bulging main commodity storage part 24 with the inclination larger toward the folding part side from a free end 23 side. One sheet 10 is turned by 180° with the folding part 15 as a pivot to fit the inner peripheral wall 11 to the outer peripheral wall 21.
