PROBLEM TO BE SOLVED: To provide a hot dip aluminized steel sheet excellent in the heat resistance and the corrosion resistance used for mainly base stock for gas exhausting system in a motor car, building material, home electric appliances, various heating devices, etc., and the producing method thereof. SOLUTION: On the steel sheet surface where the content of Ti, Mn, etc. in the components of the steel, is regulated, an intermetallic compound coated layer containing minute content of Mg is produced, and thereby, higher heat resistance than that of the conventional steel sheet is displayed, and further, on the surface of this intermetallic compound coated layer, an aluminum coated layer adding Si, Fe, Mg or further, Ca is provided to obtain the hot dip aluminized steel sheet excellent in the heat resistance and the corrosion resistance.
