There are provided a magnetic material for a magnetic refrigeration apparatus, which improves magnetic refrigeration efficiency by the wide operation temperature range of it, AMR bed using the magnetic material, and a magnetic refrigeration apparatus. The magnetic material is used for the magnetic refrigeration apparatus using a liquid refrigerant, formed by approximately uniformly blending at least two kinds of magnetic particles having different magnetic transition temperatures, and the magnetic particles exhibit an approximately spherical shape with maximum diameter of 0.3 mm or more to 2 mm or less. The AMR bed is filled with the magnetic particles.
