PROBLEM TO BE SOLVED: To provide a carburized component which allows carburization inhibition in a gas carburization method to be suppressed. ! SOLUTION: The carburized component according to the present invention contains C: 0.10 - 0.30%, Si: 0.05 - 1.00%, Mn: 0.50 - 2.00%, P: 0.030% or less, S: 0.030% or less, Cu: 0.50% or less, Ni: 1.00% or less, Cr: 0.25 - 1.95%, Mo: 1.00% or less, S-Al: 0.010 - 0.050%, N: 0.005 - 0.030%, and the balance comprising Fe and inevitable impurities. The carburized component has a J13 of 21 HRC or more in a hardenability testing method defined in JIS G0561. Thickness of Cr oxide layer formed in a surface layer of the carburized component in a temperature-raising process to a predetermined gas carburization temperature is set to be 4.9 μm or less. !
