The object of the present invention is to both reduce costs and improve magnetic characteristics of rare-earth bond magnets in which magnetic material is bound with a binding agent. In order to achieve this object, magnetic characteristics of a magnet are improved by performing cold forming on rare-earth magnetic powder by itself with no resin added (Step 2). Then, in order to provide strength for the magnet, a low-viscosity SiO 2 precursor is infiltrated and thermoset in the magnet shaped body (Step 3). As a result, it is possible to obtain a rare-earth bond magnet in which magnetic characteristics are improved and costs are reduced. |
