An accumulator has a tank and a desiccant. The tank separates refrigerant flowing to the tank into vapor-phase refrigerant and liquid-phase refrigerant, therein stores the liquid-phase refrigerant, and emits the vapor-phase refrigerant toward a suction side of a compressor. The desiccant is disposed in the tank and removing a water content from the refrigerant. Liquid-phase refrigerant included in the refrigerant flowing to the tank drops downward from a location that is located above the desiccant, and is stored in a lower portion in the tank. Vapor-phase refrigerant included in the refrigerant flowing to the tank is drawn through a suction port that is located above the desiccant to flow out of the tank. At least a part of the desiccant is exposed to vapor-phase refrigerant under a normal condition, and the desiccant is located at a location that is away from a dropping route of liquid-phase refrigerant in the tank.
