Abstract: A compressor is a compressor for a refrigeration cycle apparatus that performs a refrigeration cycle using a refrigerant containing a hydrofluoroolefin and a refrigeration oil containing a polyol ester or a polyvinyl ether. The compressor includes a sliding portion. The sliding portion is formed of an aluminum alloy containing from 5 wt % to 25 wt % of silicon. The refrigeration oil contains an acid scavenger or an oxygen scavenger and satisfies the following relational formula: total content (wt %) of acid scavenger and oxygen scavenger in refrigeration oil≥(2.3+2.6×(hydrofluoroolefin content (wt %) in refrigerant)−1.6×(silicon content (wt %) in sliding portion))/100.
