Zusammenfassung:	PURPOSE:To obtain the soft magnetic sintered alloy having good precision and good magnetic characteristics by mixing Fe-Co-V series material powder contg. the mixed powder of Fe-Co alloy powder and Fe-V alloy powder in which the content of V is prescribed with thermoplastic resins, kneading the mixture, subjecting it to compacting and thereafter executing degreasing and sintering. CONSTITUTION:Fe-Co-V series material powder contg. the mixed powder of Fe-Co water atomizing powder or gas atomizing powder including 0.5 to 15% V with Fe-V alloy powder obtd. by mechanical grinding or the like is prepd. In the material powder, 0.5 to 15% V shall be incorporated. Furthermore, the average grain size of the material powder shall be regulated to 5 to 15mum and the maximum grain size to
