To provide a non-cured heat-resistant magnetic molding using rare earth magnetic powder, capable of preventing self-disintegration under its use at high temperatures by combinedly using a specified low-density polyethylene resin with a specified elastomer.

This non-cured heat-resistant magnetic molding is obtained by including a binder component and 30-70 vol.% rare earth magnetic powder based on the whole volume, wherein the binder component comprises 100 pts.wt. at least one elastomer selected from chlorinated polyethylenes and EPDM and 5-150 pts.wt. low-density polyethylene resin having 90-200°C softening temperature.
