PROBLEM TO BE SOLVED: To avoid an excessive pressure onto an egg even though a tray is bent caused by weight of the eggs at the time of holding both ends of the tray in the pipe-molded egg storage tray. SOLUTION: The egg storage tray keeps an egg storage recessed section 10, the opening of which forms an approximately square shape, arranged in a lattice shape, and hand-held sections 18, 19 installed on both ends in the longitudinal direction of the tray. The egg storage recessed section 10 has a bottom section 11 formed in an about R-square and making each direction form in the direction of each side of the tray at an approximately half of a right angle, and inner walls 12 (12b and 12e), 13 ranged from four sides and R-sections of four corners of the bottom section 11 to the opening. R-section connecting inner walls 12b, 12e raised from the R-sections of four corners are ranged with respective side sections 15/14 of the opening, and the side section connecting inner wall 13 raised from four sides is ranged with each ridge section 16 of the opening. Distances S12b/S12e between corresponding sections of the R-section connecting inner walls 12b-12b/12e-12e facing by holding the bottom section 11 are arranged to be larger than that of the distance S13 between corresponding sections of the side section connecting inner walls 13-13.
