According to the present invention, an air conditioner includes a refrigerant-air heat exchange portion having plural refrigerant evaporation passages and heat exchanging between refrigerant flowing in the plural refrigerant evaporation passage and air passing around the plural refrigerant evaporation passages, a refrigerant-refrigerant heat exchange portion having an inlet refrigerant passage and an outlet refrigerant passages and heat exchanging between refrigerant flowing in the inlet refrigerant passage and refrigerant flowing in the outlet refrigerant passage, a pressure reducing unit placed in an upstream side of the plural refrigerant evaporation passages, and a unit case having an air flow passage therein. The refrigerant-air heat exchange portion is contained in the air flow passage, and the unit case contains the refrigerant-refrigerant heat exchange portion outside the air flow passage. Since the refrigerant-refrigerant heat exchange portion is contained outside the air flow passage in the unit case, the air passing in the air flow passage will not collide with the refrigerant-refrigerant heat exchange portion. Thus, air flow is restrained from being turbulent. In this way, uneven wind speed distribution is not formed in the air passing around the plural refrigerant evaporation passages of the refrigerant-air heat exchange portion, and therefore, distribution of the temperature in the air is not caused in the refrigerant-air heat exchange portion.
