A gas storage apparatus for use in storing a gas including methane as a main component thereof is disclosed. The apparatus includes an entrance/exit opening for allowing entrance or exit therethrough of a gas to be stored, a gas-tight maintaining mechanism capable of maintaining the gas under a pressurized state inside a container, and a pressure vessel which may be constantly maintained at a normal temperature. The pressure vessel accommodates therein an organometallic complex having a one-dimensional channel structure.
