This reprocessed component (100) is provided with a carburized layer (10) on the surface thereof, and has, in the carburized layer (10), three layers including a first cured layer (1), a second cured layer (2), and a third cured layer (3) in the stated order adjacent to each other in the depth direction from the surface and each having a greater hardness than a core part (20), the first cured layer (1) having the highest hardness among the three layers, and the second cured layer (2) having the lowest hardness among the three layers. L'invention concerne un composant retraité (100) comportant une couche carburée (10) ) à sa surface et présentant, dans la couche carburée (10), trois couches comprenant une première couche durcie (1), une deuxième couche durcie (2) et une troisième couche durcie (3) dans l'ordre indiqué, mutuellement adjacentes selon la direction de la profondeur à partir de la surface et présentant chacune une dureté supérieure à celle d'une partie centrale (20), la première couche durcie (1) présentant la plus haute dureté des trois couches et la deuxième couche durcie (2) présentant la plus faible dureté des trois couches. この再処理部品（１００）は、表面に浸炭層（１０）を備え、浸炭層（１０）内において、表面から深さ方向に、いずれも心部（２０）よりも硬度が高い第１硬化層（１）、第２硬化層（２）及び第３硬化層（３）の三層を順に隣接して有し、第１硬化層（１）は三層の中で硬度が最も高く、かつ、第２硬化層（２）は三層の中で硬度が最も低い。
