Claim 9:
10. A soft magnetic material comprising:
first soft magnetic particles; and
second soft magnetic particles having a larger average particle size than the first soft magnetic particles,
wherein the first soft magnetic particles have an average particle size in a range of 0.5 to 10 μm, and
the first soft magnetic particles have a hydrocarbon group with a straight-chain moiety having 6 or more carbon atoms on their surfaces,
the first soft magnetic particles have a lubricity value of 2.5%/mm or more, the second soft magnetic particles have a lubricity value of less than 2.0%/mm, the lubricity value being represented by the following formula,

Percentage of stress relaxation (%)=(Maximum indentation load−Indentation load at the beginning of lateral sliding)/Maximum indentation load×100; and

Lubricity (%/mm)=Percentage of stress relaxation (%)/Final powder layer thickness (mm).
