         5 . The air-conditioning apparatus according to  claim 2 , comprising:
 a control unit configured to cause an output of the irradiation device during a cooling operation in which air is cooled by the heat exchanger to be larger than an output of the irradiation device during a heating operation in which air is heated by the heat exchanger.   
     
     
         6 . The air-conditioning apparatus according to  claim 2 , comprising:
 a control unit configured to set the irradiation device to an ON state when an operation of the air-conditioning apparatus is stopped.   
     
     
         7 . The air-conditioning apparatus according to  claim 2 , comprising:
 a drain pan,   wherein the irradiation device emits the ultraviolet ray toward the drain pan.   
     
     
         8 . The air-conditioning apparatus according to  claim 2 , wherein the irradiation device emits the ultraviolet ray toward the heat exchanger. 
     
     
         9 . The air-conditioning apparatus according to  claim 2 , comprising:
 a fan configured to convey air,   wherein the irradiation device emits the ultraviolet ray toward the air conveyed by the fan.   
     
     
         10 . The air-conditioning apparatus according to  claim 2 , wherein the heat exchanger is configured to cool air by the heat medium, and
 wherein the irradiation device is disposed on an upstream side of an air flow with respect to the heat exchanger.   
     
     
         11 . The air-conditioning apparatus according to  claim 2 , wherein the LED faces a downstream side of an air flow. 
     
     
         12 . The air-conditioning apparatus according to  claim 2 , wherein the heat conductor is a part of the fins. 
     
     
         13 . The air-conditioning apparatus according to  claim 1 , comprising:
 a heat conductor configured to connect the irradiation device and the heat-dissipating unit.   
     
     
         14 . The air-conditioning apparatus according to  claim 13 , wherein at least one of the heat-dissipating unit and the heat conductor is a metal material. 
     
     
         15 . The air-conditioning apparatus according to  claim 13 , wherein a heat transfer rate of at least one of the heat-dissipating unit and the heat conductor is 80 w/m·K or greater. 
     
     
         16 . The air-conditioning apparatus according to  claim 1 , comprising:
 a casing having an air passage formed therein,   wherein the heat-dissipating unit includes a first heat-dissipating member fixed to an inner surface of the casing.   
     
     
         17 . The air-conditioning apparatus according to  claim 16 , wherein the first heat-dissipating member includes a metal plate or a metal tape. 
     
     
         18 . The air-conditioning apparatus according to  claim 1 , comprising:
 a casing having an air passage formed therein,   wherein the heat-dissipating unit includes a second heat-dissipating member constituted by a part of the casing.
