A refrigerant compressor includes a compressor section, driver, a first
contact section and a second contact section. The compressor section is
accommodated in a closed container for compressing refrigerant gas. The
driver drives the compressor section. The first and second contact
sections are brought into contact with each other or they slide with each
other by driving the compressor section. On the surface of each one of
the contact sections, at least one of plural recesses uniformly placed or
a mixed layer, to which molybdenum disulfide (MoS.sub.2) is bound, is
formed. The foregoing structure allows increasing the abrasion resistance
of the first and second contact sections.
