PURPOSE: A temperature sensor fixing structure is provided to improve workability and reduce manufacturing cost while increasing a coupling force between the temperature sensor and sensor holder. CONSTITUTION: A structure comprises a sensor holder(160) coupled to a portion of a return band pipe(154) of a heat exchanger(140), and a temperature sensor(170) inserted in the sensor holder and which senses the temperature of refrigerant transmitted from the return band pipe through the sensor holder. The sensor holder is shaped as a tube having an opening(161) formed at the top portion of the sensor holder, and has a fixing member(162) protruded inwardly at a portion of the periphery of the sensor holder and which tightly fixes the temperature sensor inserted into the sensor holder. The temperature sensor has a fixing groove(171) formed at an outer periphery of the temperature sensor and which receives the fixing member of the sensor holder. The length of the protrusion of the fixing member of the sensor holder is longer than the depth of the fixing groove of the temperature sensor so as to prevent the temperature sensor from being escaped from the sensor holder when the fixing member is inserted into the fixing groove.
