A foamed plastic container in which the cell diameters vary along a gradient so as not to decrease the content protection performance, in a manner quite different from the foamed cells distributed in the conventional foamed containers. The foamed plastic container has a container wall formed by using a plastic material and in which foamed cells are distributed, the lengths of the foamed cells in the surface direction of the container wall decreasing from the outer surface of the container toward the inner surface thereof. |
