PROBLEM TO BE SOLVED: To provide a storage container enabling a stored substance to be extracted with minimum wastage while having inexpensive manufacturing cost. SOLUTION: The storage container is provided with a tube-shaped storing portion 2 formed of a resin having an extraction opening 2a enabling a stored substance to be sucked in a center area on one end side, and a circular opening on the other end side, and a bag-shaped storing portion 3 which is welded along the circular opening of the tube-shaped storing portion 2, enters inside the tube-shaped storing portion to be able to come into intimate contact with an inner surface of the tube-shaped storing portion in sucking through the extraction opening 2a, and is formed of a thin film in the shape of a bag to be a non-independent body, where the tube-shaped storing portion 2 changes in cross-sectional shape from a circular shape to an elliptical shape toward one end side from the other end side.
