Liquid film 7 is formed on the surface of a porous body 2 provided with a hydrophobic layer 6 a and hydrophilic layer 6 b, by moving thereon an ionic liquid having a selective absorption capacity of specific gas, and the specific gas within the gas to be processed is absorbed into the liquid film 7 by bringing pressurized gas to be processed into contact with the liquid film 7 . The specific gas is, for example, a carbon dioxide gas and the ionic liquid is, for example, an imidazolium salt. The specific gas absorbed into the liquid film 7 is passed through the porous body 2 by use of a difference in pressure, and is collected on a low pressure side 11 . The specific gas absorbed into this liquid that has been collected is separated into gas and liquid by a separator 8 , and the specific gas is released and collected.
