A gas separation method is provided in which, when separating a first component and a second component from a mixed gas containing a plurality of components by using a pressure swing adsorption method, these components can be efficiently recovered and cost reduction can be achieved. Between an adsorption step and a regeneration process step, which use a first adsorption column containing a first adsorbent on which the first component is less readily adsorbable and the second component is absorbable, and a second adsorption column containing a second adsorbent on which the first component is readily adsorbable and the second component is less readily adsorbable, an equalization depressurization step and an equalization pressurization process step, in which the pressure of the first and second adsorption columns is equalized, is carried out.
