Food container with reduced elution of hazardous substances

A food container comprising:

• a bilayer structure which includes a foamed layer formed on an inner layer of the container and having an average cell size of 100 to 500 μm;
• and
• a resin layer formed on an outer layer of the container and laminated on one surface of the foamed layer,
• wherein the resin layer is formed of a resin having a repeating unit of Formula 1 below:
• wherein m and n represent mole fractions of repeating units, and range from 1 to 100, respectively,
• wherein 90% or more of cells of the foamed layer are closed cells (DIN ISO4590),
• wherein the foamed layer is a foam sheet of a polyethylene terephthalate resin, and the resin layer is a coating layer of a polyethylene terephthalate resin,
• in which a difference in temperature between an inside and an outside of the container is 10° C. or more, which is measured, under ambient conditions at room temperature, two minutes after water of 60 to 100° C. is placed into the container at 70% (v/v).
