PROBLEM TO BE SOLVED: To provide a gas adsorbing sheet capable of efficiently adsorbing and collecting one or more kinds of gas requiring different adsorbing mechanisms at the same time even if a smaller amount of an adsorbent is used. SOLUTION: Adsorbent particles having a physical adsorbing action of gas are interposed between two air permeable sheets and at least one air permeable sheet of them has a chemical adsorbing action of gas.
