To enable superheating of foods quickly in a uniform distribution by arranging a tray body having a base structure made of a resin material and a cover having a film made of a resin material.
A tray body 1 comprises a base structure 6 made of a resin material forming an outer surface 7 and a rim of a bottom part. The base structure 6 contains an upper diffusion layer 19 comprising aluminum, non- magnetic metal, as highly heat conductive body at a part 3 accepting a cover 2 and a visible surface 20 is covered with a layer of black polytetrafluoroethylene or black enamel for promoting the radiation of heat to foods. The cover 2 has a visible surface covered with a layer of black polytetrafluoroethylene or black enamel and contains a resin film 22 as thermosetting resin material which is adhered onto a lower diffusion layer 23 comprising aluminum, non-magnetic metal, as highly heat conductive body. The lower diffusion layer 23 contacts an intermediate member 24 which is housed between the layer and the film 22 and comprises a material heated by magnetic induction.
