For the purpose of increasing the area of an adsorbent to be in contact with the air, a heat exchanger ( 47, 49 ) includes: a fin set ( 59 ) including a plurality of fins ( 57 ) arranged parallel to each other with an interval therebetween; a framework ( 61 ) arranged to surround end faces of the fin set ( 59 ) in the arrangement direction of the fins and end faces of the fin set ( 59 ) in the lengthwise direction of the fins; a serpentine heat transfer tube ( 63 ) having straight parts ( 63 a) penetrating the fin set ( 59 ) in the arrangement direction of the fins and U-shaped parts ( 63 b) protruding out of the framework ( 61 ); and a connector tube ( 65 ) for connecting the heat transfer tube with a refrigeration pipe. An adsorbent capable of adsorbing moisture from the air and desorbing the moisture into the air is supported on the surfaces of the fin set ( 59 ), the framework ( 61 ), the heat transfer tube ( 63 ) and the connector tube ( 65 ), respectively.
