A thixocast Fe-based alloy material is provided, from which a cast product having mechanical properties uniform over the whole thereof can be produced.The Fe-based alloy material comprises1.8% by weight<=C<=2.5% by weight,1.0% by weight<=Si<=3.0% by weight,0.1% by weight<=Mn<=1.5% by weight,0.5% by weight<=Ni<=3.0% by weight, andas the balance, iron (Fe) including inevitable impurities. The eutectic crystal amount Ec is in a range of 10% by weight<Ec<50% by weight.
