To provide a cooling device that can refrigerate foods and stably maintain high humidity without being limited by a region and a period. A cooling device includes a heat exchange unit that performs heat exchange between a refrigerant circulating in a freezer and air circulating in a box and an adjusting unit that maintains a state in which moisture adheres to heat transfer units of the heat exchange unit.

A vacuum adiabatic body may include: a first plate member; a second plate member; a sealing part sealing the first plate member and the second plate member to provide a third space; a supporting unit maintaining the third space; a heat resistance unit at least including a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space to decrease a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted. A side frame may be fastened to the conductive resistance sheet and the second plate member, and the side frame is fastened to an edge portion of the second plate member. Accordingly, the formation of dews may be prevented and an adiabatic effect may be improved.

A vacuum adiabatic body includes a heat exchange pipeline and a sealing plug. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing plug allows the heat exchange pipeline to pass through a first point of the first plate and a second point of the second plate without contacting a third space.
