The plurality of fins include a cutout fin provided with a cutout as a region where frost accumulates. The cutout fin is disposed at a position facing the temperature-switching compartment return port guiding the temperature-switching compartment return air in a temperature range nearest to the refrigeration temperature zone, from among the plurality of temperature-switching compartment return ports.
