Zusammenfassung:	The present invention provides a tray for frozen food enabling frozen food such as frozen sushi on the tray to be suitably thawed and to provide a frozen food package or a frozen sushi package using this tray, and a method of thawing frozen sushi in this package. The tray for frozen food 1 comprises a base 3 , concavities 2 caved in the base 3 , a surrounding wall 4 standing from the periphery of the base 3 , a flange 5 composing the top end of the surrounding wall 4 , a downward flap 6 extending downwardly from the outer peripheral edge of the flange 5 , an overhanging portion 7 overhanging outward from the lower edge of the downward flap 6 , ribs 8 formed at corners between the base 3 and the surrounding wall 4 , and bulges 9 standing from the base 3 . The tray 1 is composed of a body 1 a made of a synthetic resin and a dielectric material layer 1 b formed on the outer surface of the body 1 a. Frozen sushi 10 is disposed such that the shari ball 11 is entirely or mostly positioned within the concavity 2 and the neta 12 is entirely positioned above the level of the base 3 . The frozen sushi is thawed in such a manner that the shari ball 11 is thawed with heat transmitted from the dielectric material layer 1 b by heating the frozen food package by a microwave oven and the neta 12 is thawed with heat transmitted from the shari ball 11 after stopping heating the package in the microwave oven.
