Abstract: This magnetic refrigeration module includes a magnetic refrigeration operation unit which has a magnetic refrigeration material, and extends in a longitudinal direction, and a fixed magnetic field excitation unit and a variable magnetic field excitation unit which are disposed apart from each other in an outer peripheral direction of the magnetic refrigeration operation unit, in which the fixed magnetic field excitation unit applies a fixed magnetic field to the magnetic refrigeration operation unit, and the variable magnetic field excitation unit applies a variable magnetic field to the magnetic refrigeration operation unit when being in an ON state and does not apply the variable magnetic field to the magnetic refrigeration operation unit when being in an OFF state.
