PROBLEM TO BE SOLVED: To provide an apparatus and a method for producing a gas hydrate capable of simply and stably removing a gas-hydrate slurry having a desired slurry concentration out of a reactor, and to enable reduction of a possibility that the gas hydrate contained in circulation water may cause a blockage of a cooling unit when the apparatus is provided with a water circulation unit. SOLUTION: The apparatus for producing a gas hydrate comprises a raw material gas feeding means to feed a raw material gas 5 as a bubble into the water in a reaction vessel 1, wherein the raw material gas is brought into contact with the water under a predetermined temperature and pressure to produce a gas hydrate. The apparatus comprises a partition ring 70 of a doughnut shape which is provided at a position under the water surface in the reaction vessel 1 to divide the region under the water surface of the reaction vessel into upper and lower regions 72 and 73 which communicate with each other through an opening 71 of the partition ring 70. The apparatus further comprises a rotary vane 74 for the upper region and a rotary vane 75 for the lower region which are provided in the upper and lower regions respectively and rotated about a vertical shaft.
