To provide an instant food container which can be prevented from losing its shape or cracking due to rattling while easiness in putting in instant food can be kept while an additive ingredient can be prevented from coming under the instant food.

An upper end opening above an intermediate stage 11 in a depth direction of a peripheral wall 5 of a container body 1 is formed to be larger than an outer dimension of the instant food 6. This makes it easy to fit the instant food 6 into the container body 1. Swells 12 and 12 swelling from the stage 11 inwardly toward a base are integrally formed to protrude on opposite portions on an internal surface of the peripheral wall 5 of the container body 1. A part of an external surface of the instant food 6 is brought into contact with an internal surface 12b of the swell 12 to prevent the food 6 from rattling in the container body 1.
