To suppress as much as possible deformation caused by a carburization treatment, when manufacturing a carburized component by carburizing a high-melting metal component.SOLUTION: A method for manufacturing a carburized component by carburizing a high-melting metal component (20) includes following procedures. The high-melting metal component is held between a first holding member (21) and a second holding member (22) which are both rigid bodies, and either or both of which have a function as a carbon supply source. Hereby, a laminate (S) of the first holding member, the high-melting metal component and the second holding member is formed. Subsequently, the laminate is subjected to a carburization treatment, while being heated.SELECTED DRAWING: Figure 2 【課題】高融点金属部品を浸炭することにより浸炭部品を製造するに際しては、浸炭処理による変形を可及的に抑制することが求められている。【解決手段】高融点金属部品（２０）を浸炭することにより浸炭部品を製造する方法は、以下の手順を含む。ともに剛体であり一方または双方が炭素供給源としての機能を有する、第一挟持部材（２１）と第二挟持部材（２２）との間に、前記高融点金属部品を挟持する。これにより、前記第一挟持部材と前記高融点金属部品と前記第二挟持部材との積層体（Ｓ）を形成する。続いて、前記積層体を加熱しつつ浸炭処理する。【選択図】図２
