Refrigerant compressor and refrigeration device including refrigerant compressor

A refrigerant compressor which

• reserves lubricating oil with a viscosity of VG2 to VG100 in a sealed container, and
• accommodates therein an electric component and a compression component which is driven by the electric component and compresses a refrigerant,
• the compression component including at least one slide member comprising a base material made of an iron-based material and an oxide coating film provided on a surface of the base material, and
• the oxide coating film including:
• a portion containing diiron trioxide (Fe2O3), in a region which is closer to an outermost surface of the oxide coating film;
• and
• a silicon containing portion containing silicon (Si) which is more in quantity than silicon (Si) of the base material, in a region which is closer to the base material,
• wherein the oxide coating film includes a spot-shaped silicon containing portion that is located closer to the outermost surface of the oxide coating film than the silicon containing portion, the spot-shaped silicon containing portion being a portion containing silicon (Si) which is more in quantity than silicon (Si) contained in a region surrounding the spot-shaped silicon containing portion.
