A magnetic material has a composition expressed by the following general formula,(where, R1 is at least one kind of element selected from rare earth elements, R2 is at least one kind of element selected from Zr, Hf, Ti and Sc, T is at least one kind of element selected from Fe and Co, and X, Y, Z and Q designate numerical values satisfying 0.5<=X<1, 0.05<=Y<=0.2, 0<=Z<=0.1 and 0.1<=Q<=0.2), and includes 5 volume % or more of a Th2Ni17 crystal phase. The magnetic material has a recrystallization texture of which average grain diameter is in the range of from 0.02 to 50 mum, and is excellent in magnetic property. Such a magnetic material is obtained by giving a HDDR treatment to a mother alloy of which principal phase is a Th2Ni17 crystal phase.
