A handle-interlocking airtight boiling pot includes: a rotational body which is rotatably supported at the side of the container and is mounted to rotate between a lid opening position and a lid closing position; a hand grip part formed at an upper end of the rotational body; and an airtightly fixing part which is formed integrally with a lower part of the hand grip part and protrudes toward the lid to airtightly fix the lid to the container by pressing an upper side of the lid when the rotational body is located at the lid closing position. The lid includes: a retaining protrusion formed at an upper side of an edge portion of the lid to catch and retain the airtightly fixing part of the rotational body at the lid closing position; and a contact groove part with which a contact surface of the airtightly fixing part gets in contact.
