An air conditioner includes a heat exchanger including a plurality of refrigerant tubes, a distributor disposed on one side of the heat exchanger to divide a refrigerant so that the refrigerant flows into a plurality of flow paths, a plurality of capillary tubes extending from the distributor toward the plurality of refrigerant tubes, a guide tube guiding an introduction of the refrigerant into the distributor, an inlet tube connected to an inlet-side of the distributor, and a bending part disposed between the guide tube and the inlet tube to switch a flow direction of the refrigerant. The inlet tube extends in a horizontal direction or an inclined direction to guide a liquid refrigerant of a two-phase liquid refrigerant so that the liquid refrigerant flows into a lower portion of the inlet tube.
