To prevent attachment of dust and moisture to various electric components and to cool a heating element with respect to a refrigerating machine.

This refrigerating device includes a refrigerant circuit for performing a refrigerating cycle by circulating a refrigerant, the electric components for controlling components of the refrigerant circuit, and an electric component box (31) receiving the electric components. This refrigerating device includes a refrigerant jacket (41) for cooling the electric component box (31). In the electric component box (31), a liquid for insulation is filled so that heating elements (61, 62, 63) among the electric components are immersed.
