An aluminum-iron-plated steel sheet including a base steel sheet and an aluminum-based plating layer on a surface of the base steel sheet. The aluminum-based plating layer includes an alloyed layer on the surface of the base steel sheet and an aluminum layer on the alloyed layer. The alloyed layer may be formed of one or more of Fe3Al, FeAl(Si), Fe2Al5, and FeAl3. A thickness of the alloyed layer may be 90% or more of a thickness of the aluminum-based plating layer. A surface fraction of Ti may be 2% or less and a surface fraction of Zn may be 1% or less, as observed on the surface of the aluminum-based plating layer.
