Claim 12:
13. An Fe-based alloy for melting-solidification shaping consisting of:
S≤0.05 mass %;
P≤0.05 mass %;
18.0 mass %≤Co<25.0 mass %;
12.0 mass %≤Mo≤20.0 mass %;
0.2 mass %≤Mn≤5.0 mass %,
4.11 mass %≤Ni≤10.0 mass %, and
0 mass %≤Si≤1.0 mass %,
with the balance being Fe and unavoidable impurities,
and satisfying the following expressions (1) and (2), where [M] represents a content of an element M expressed in mass % basis,

58≤[Co]+3[Mo]≤95  (1)

A/B≥1.6  (2)

where

A=[Co]+[Ni]+3[Mn], and

B=[Mo]+[Si],

wherein, based on the Fe-based alloy for melting-solidification shaping comprising no Si, the expression (2) is calculated using [Si]=0.
