A bottom structure of a biaxially-oriented blow-molded bottle-shaped container is made of a synthetic resin and includes a neck, a shoulder, a body and a bottom. The bottom has a connecting cylindrical wall, a tapered-cylindrical wall, a bottom wall and a grounding wall. A diameter of the tapered-cylindrical wall is decreased downwardly at a certain inclined angle. The bottom wall is domed to an inside of the container. The grounding wall is in a ring plate shape and arranged between a lower edge of the tapered-cylindrical wall and a lower edge of the bottom wall. Each of groove ribs is formed from an upper edge of the tapered-cylindrical wall through the grounding wall to the lower edge of the bottom wall. The groove ribs are arranged with isometric center angle, and extend radially.
