PROBLEM TO BE SOLVED: To immediately cool eggs packaged in a transportable form, thereby securely retaining quality, and to facilitate an operation such as preliminary cooling operation when using eggs. SOLUTION: An egg packaging structure is such that eggs E are stored in an internal member 6, then in a corrugated board external member 1, and thus packaged. The internal member 6 and the external member 1 have vents 4, 5, and 9 formed to exchange a flow of air outside the external member 1 and a flow of air inside the internal member 6. The vents 4 and 5 are made in the external member 1 in such positions that they are in the sideways middle of a first side face 2 defining the width of the external member 1 and they are a half the width of the first side face 2 or the substantially same distances from both ends of a second side face 3 that is adjacent to the first side face 2.
