Zusammenfassung:Provided are a cascade unit and a refrigeration cycle apparatus capable of cooling an electric component. Provided is a cascade unit (2) of a refrigeration cycle apparatus (1) including a primary-side refrigerant circuit (5a) that includes a primary-side heat exchanger (74) and through which a primary-side refrigerant flows, a secondary-side refrigerant circuit (10) that includes a secondary-side compressor (21) and a utilization-side heat exchanger (52a, 52b, 52c) and through which a secondary-side refrigerant flows, and a cascade heat exchanger (35) that exchanges heat between the primary-side refrigerant and the secondary-side refrigerant, the cascade unit including the secondary-side compressor (21), the cascade heat exchanger (35), a first electric component (91) that drives the secondary-side compressor (21), a first cooling portion (11a) that cools the first electric component (91) with the secondary-side refrigerant flowing through the secondary-side refrigerant circuit (10), a cascade casing (2x) that accommodates the secondary-side compressor (21), the first electric component (91), and the first cooling portion (11a).
