PROBLEM TO BE SOLVED: To provide a method for uniformly producing a gas hydrate in a porous material while preventing the intrusion of air, water, etc. SOLUTION: A vessel 2 capable of keeping the pressure at a constant level is charged with a stock gas, steam and a porous material 7, the porous material 7 is transferred from a high-temperature zone having a temperature higher than the critical forming temperature of the gas hydrate to a low-temperature zone having a temperature lower than the critical forming temperature of the gas hydrate to uniformly form the gas hydrate in the porous material 7.
