A food container for cooking through use of a microwave oven includes a container adapted to contain food and having a hole and a pressure regulation valve attached to the food container to close the hole. The pressure regulation valve includes a cover film having an area sufficient to cover the hole, an adhesive layer applied over the surface of the cover film facing the food container, and a separator film disposed between the adhesive layer and the food container and having an area larger than that of the hole but smaller than that of the cover film. When food contained in the container is cocked in a microwave oven, the food is heated so that moisture is produced from the food. Until the vapor pressure within the food container reaches a predetermined level, the pressure regulation valve remains closed. When the vapor pressure within the food container reaches the predetermined level, the cover film partially separates from the food container in order to relieve the vapor pressure. The pressure regulation valve may include a gas-permeable film for preventing hot liquid from spouting from the hole of the container.
