To provide a container made of resin wherein the bottom thereof can be elevated by expanding and contracting the bottom without breaking the bottom by pushing it, so that even if the amount of contents remaining in the container becomes small, the contents can be taken out easily.

In a part of a bottom surface (bottom cover member 4) of the container made of resin, an annular tapered part comprising at least a first tapered part 8 which is tapered inwardly downwardly from the outer peripheral side of the container and a second tapered part 9 connected to the inner peripheral side of the tapered part 8 and tapered inwardly upwardly from the outer peripheral side is formed. And a large number of folds (pleats) PL are formed on the part 8 and the part 9, each of the folds extending in radial directions. And the inner peripheral side of the part 8 is upwardly moved with respect to the outer peripheral side thereof to elevate an inner peripheral side planar part 10.
