To provide a cooking pot which prevents generation of boil-over through a gap between the pot and the lid by discharging steam in the cooking space to lower pressure to prevent generation of boil-over before generating boil-over through a gap between the pot body and the lid by rising pressure in the cooking space has a mechanism for circulating condensed water from a part of steam.

Before generating boil-over through a gap between the pot body and the lid, a needle valve is actuated so as to discharge steam in the cooking space out to temporarily store condensed water in a water storage space and the water is circulated when the needle valve is opened again.
