Abstract
Provided is a hard particle in which Cr and W, that are quickly diffused in Mo, are present at the same time as Ni and Mn. Specifically, the hard particle contains Cr: 5% by mass to 20% by mass, W: 2% by mass to 19% by mass, Mo: 25% by mass to 40% by mass, Ni: 10% by mass to 22% by mass, Mn: 10% by mass or less, C: 2.0% by mass or less, Si: 2.0% by mass or less, and a remainder: Fe and unavoidable impurities.
