There is provided a method for producing a magnetic refrigeration module. The method comprises: a step (1) of preparing a mixture powder A containing an La(Fe,Si)-based alloy powder, an M powder, and optionally an organic binder, the La(Fe,Si)-based alloy powder having a main phase with an NaZn-type crystal structure, and the M powder containing a metal and/or an alloy and having a melting point of 1090&#xb0; C. or lower; a step (2) of subjecting the mixture powder A to a heat treatment in a reducing atmosphere at a temperature close to the melting point of the M powder to obtain a sintered body B; and a step (3) of subjecting the sintered body B to a hydrogenation treatment in a hydrogen-containing atmosphere.
