A refrigeration cycle apparatus includes a refrigerant and a refrigeration cycle circuit. The refrigeration cycle circuit includes a heat exchanger and a compressor, and circulates the refrigerant. The refrigerant is a single hydrofluoroolefin (HFO)-based refrigerant or a mixed refrigerant. In the mixed refrigerant, an HFO-based refrigerant is mixed at a mixing ratio of 10% by weight or more. The compressor includes a motor. The motor includes a resin component. The resin component includes a polyimide having a terminal blocked with a terminal group.
