Abstract
A machine part (an oil-impregnated bearing (1)) is obtained by subjecting a green compact to heat treatment in an oxidizing atmosphere (for example, in air), the green compact being obtained by compacting and forming raw material powder containing iron powder and copper powder. Iron particles (10) and copper particles (20) are bonded to each other with oxide films (11) and (21) formed on surfaces of the particles. The oxide films (11) and (21) each have a maximum thickness of 1 μm or less in a region at a depth of 300 μm±10 μm from a surface of the green compact.
