Abrégé[Problem] To remove foreign matter dissolved in refrigeration oil without lowering the operating efficiency of an air conditioner. [Solution] The present invention comprises: a recessed reservoir that is connected to the gas flow path of a refrigeration cycle, which is provided with a compressor, an expansion mechanism, an evaporator, and a condenser and circulates a refrigerant containing at least refrigeration oil, and stores a mixture of the liquid-state refrigerant and refrigeration oil, or the liquid-state refrigeration oil; and a capture material that is housed in the reservoir and captures foreign matter contained in the mixture of the liquid-state refrigerant and the refrigeration oil or in the liquid-state refrigeration oil.
