In magnetic refrigeration wherein a magnetic Ericsson cycle or a magnetic Stirling cycle is realized, the present invention forms a heat path by which heat of a magnetic working substance at an isofield stage of high magnetic field or an isomagnetization stage of high magnetization is given to the magnetic working substance at an isofield stage of low magnetic field or an isomagnetization stage of low magnetization.

In a magnetic refrigerator having a working substance for magnetic refrigeration which generates heat isothermally as a magnetic field is supplied thereto and which absorbs heat isothermally as a magnetic field is released therefrom, heat exchange means for radiating heat to outside when the working substance generates the heat isothermally and for absorbing heat from the outside when the working substance absorbs heat isothermally; means for producing a varying magnetic field that is applied to the working substance to produce a magnetic refrigeration cycle; and heat transport means made of an anisotropic thermal conductor for establishing a heat path between an isofield stage of high magnetic field and an isofield stage of low magnetic field, or between an iosmagnetization stage of high magnetization and an isomagnetization stage of low magnetization in the two isofield stages or two isomagnetization stages of the magnetic refrigeration cycle.
