A metal powder for powder metallurgy includes particles, which contain Fe as a principal component, Cr in a proportion of 10 to 30 mass%, C in a proportion of 0.1 to 2 mass%, and Si in a proportion of 0.2 to 1.5 mass%, and in which when one element selected from the group consisting of Ti, V, Y, Zr, Nb, Hf, and Ta is defined as a first element, and one element selected from the group, and having a higher group number in the periodic table than that of the first element or having the same group number in the periodic table as that of the first element and a higher period number in the periodic table than that of the first element is defined as a second element, the first element is contained in a proportion of 0.01 to 0.5 mass%, and the second element is contained in a proportion of 0.01 to 0.5 mass%, wherein the number of crystals in the cross section of the particle is 1 or more and 5 or less on average. |
