摘要：
A dental component is formed from a sintered body of a metal powder having particles containing Co, Cr, Mo, and Si as constituent components. In the particles, Co is contained as a main component, the content of Cr is 26% by mass or more and 35% by mass or less, the content of Mo is 5% by mass or more and 12% by mass or less, and the content of Si is 0.3% by mass or more and 2.0% by mass or less. The dental component has excellent proof stress and corrosion resistance. It is preferred that a part of Si in the sintered body is contained as silicon oxide, and the ratio of the content of Si contained as the silicon oxide to the content of Si in the sintered body is 20% or more and 80% or less.
