A steel sheet for carburizing, which exhibits more excellent ultimate deformability before carburization, and a method for producing the same are provided. The steel sheet of the present invention is, by mass, C: 0.02% or more and less than 0.30%, Si: 0.005% or more and less than 0.5%, Mn: 0.01% or more and less than 3.0%, P: 0.1% or less, S: 0.1% or less, sol .Al: 0.0002% or more and 3.0% or less, N: 0.2% or less, the remainder is composed of Fe and impurities, the X-ray random strength of the {100}<011> to {223}<110> Defense Forces of ferrite crystal grains The ratio of the number of carbides having an average ratio of 7.0 or less, an average equivalent circle diameter of the carbides of 5.0 μm or less, and an aspect ratio of 2.0 or less is 80% or more with respect to the total carbides, and the ratio of the number of carbides present in the ferrite grains, It is 60% or more with respect to all carbides. |
