Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas removal filter scarcely dropping an adsorbent and having a high ventilation property and a long life. SOLUTION: The gas removal filter is characterized in that at least one face between the upstream face 4 and the downstream face 5 of a formed body 11 obtained by bonding a granular adsorbent 1 with a powdered hot melt resin 7 is coated with a bonding body 12 of the powdered hot melt resin. Since at least one face between the upstream face 4 and the downstream face 5 which have the adhesion strength weaker than other parts and thus may possibly drop the granular adsorbent 1 is coated with a bonding body 12 of the powdered hot melt resin, the gas removal filter can suppress the dropping of the granular adsorbent 1 from the gas removal filter itself and at the same time the gas removal filter can be handled without directly touching the formed body 11 and accordingly possibility of contamination of the gas removal filter can be lowered when handling.
