Provided is a steel sheet for carburization which is more ductile and a method for producing the same. The steel sheet according to the present invention is characterized by containing, by mass%, C: not less than 0.02% and not more than 0.30%, Si: not less than 0.005% and not more than 0.5%, Mn: not less than 0.01% .Al: 0.0002% or more than 3.0%, N: 0.2% or less, Ti: at least 0.010% containing less than 0.150%, and the balance being made of Fe and impurities, and the number of carbides per 1000㎛ 2 less than 100, The number ratio of carbides having an aspect ratio of 2.0 or less is 10% or more with respect to the total carbides, the average circle equivalent diameter of carbide is 5.0 mu m or less, and the average crystal grain diameter of ferrite is 10 mu m or less. |
