PROBLEM TO BE SOLVED: To provide an adsorption filter or the like which is capable of improving regeneration efficiency even when heating the adsorption filter or the like from one side.SOLUTION: An adsorption filter includes a base material formed so that air passes, an adsorbent provided on the base material, and a plurality of wires having higher thermal conductivity than that of the base material and provided along the direction through which the air of the base material passes. By such configuration, even when arranging a heating device only on one side of the adsorption filter, the heated state is the same as when arranging the heating device on both sides of the heating device of the adsorption filter. Consequently, the regeneration efficiency of the adsorbent filter is improved.
