A magnetic material has a composition expressed by the following general formula,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.
