The present invention relates to a double cooking container having improved stability and improved heating efficiency. Particularly, the double cooking container has a double structure in which an inner cylinder is formed inside an outer cylinder, a heat retaining space formed by inserting the inner cylinder into the inside of the outer cylinder and thus maintaining a predetermined interval between the bottom surface of the outer cylinder and the bottom surface of the inner cylinder, and a side fluid channel formed between the outer cylinder and the inner cylinder to communicate with the heat retaining space, wherein a plurality of discharge holes communicating with the side fluid channel are formed in the outer cylinder, and the entire sectional area of the discharge holes is controlled to be within a predetermined range in order to implement high heating efficiency as well as ensure stability. |
