PROBLEM TO BE SOLVED : To provide a rare-earth-iron-nitrogen based magnetic powder excellent in both coercive force and remanent magnetization and further heat resistance, and to provide a method for manufacturing the same. SOLUTION : In the rare-earth-iron-nitrogen based magnetic powder with Th2Zn17 crystalline structure, the rare-earth-iron-nitrogen based magnetic powder is expressed by the general formula : RvFe(100-v-w-x)NwMx (here, R is at least one kind out of lanthanoid elements including Y, M is Zr or Ti, v meets 3≤v≤30, w meets 5≤w≤15, if M is Zr, x meets 0
