PROBLEM TO BE SOLVED: To rapidly raise temperature at the startup and certainly perform a desired thermal insulation for a certain period in a compact structure by forming a microwave absorbing heater layer on at least upper surface of the central part of a pottery container body with a high table through which microwave passes. SOLUTION: A container body 2 forming this thermal insulating container 1 is formed plate-like having a high table 3 using pottery, and then is baked in a predetermined high temperature to microwave-permeable structure. A microwave absorbing heater layer 4 is formed on the upper surface of the central part of the container body 2. This thermal insulating container 1 is stored in a microwave oven, microwave is radiated, and the microwave absorbing heater layer 4 is heated to high temperature to heat the thick central part for heat accumulation. Thus, foods are heated and simultaneously thermal insulation is ensured for a certain period. At this time, existence of the high table 3 allows an air insulating layer to be formed under the lower surface of the container body 2, so that a thermal insulation effect of the foods can be provided effectively.
