Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a filter and a filter structure for adsorbing ammonia gas, each of which exhibits excellent performance when ammonia gas is adsorbed and can prevent acetic acid from being generated owing to the decomposition of PGMEA (propylene glycol monomethyl ether acetate) in the atmosphere containing PGMEA. SOLUTION: This plate-shaped filter for adsorbing ammonia gas is obtained by depositing zirconium phosphate of 0.5-4 pts. wt. on a fibrillated aramid fiber or a fibrillated acrylic fiber of 1 pt. wt. and subjecting zirconium phosphate-deposited fiber to wet papermaking. This ammonia gas adsorbing filter structure having a corrugated honeycomb structure is obtained by stacking the plate-shaped filter and a corrugated molding of the plate-shaped filter.
