To enable a heating container which generates heat by the microwave of a microwave oven to easily be carried without burns.

This container for heating by microwave oven is constituted of an internal container 1 for housing an article to be heated which generates heat by the microwave, and an external container 3 which is placed in a manner to cover the outside of the internal container 1. An overhang piece 1a is formed on the upper end external edge of the internal container 1. A step section 3b which engages with the overhang piece 1a of the internal container 1 is formed on the upper end internal edge of the external container 3. The external container 3 is made to have a bottom deeper than the internal container 1 so that a space A may be formed between the containers when they are stacked. A high table 3d is formed on the lower surface of the external container 3, and a ventilation hole 3e is formed on the lower surface of the external container 3. Thus, air in the space A which is heated after the heating is discharged from the ventilation hole 3e to increase the cooling property of the external container 3.
