摘要： A slide member of the present invention is used in a slide unit which is included in a refrigerant compressor for compressing a refrigerant and provided inside a sealed container which reserves lubricating oil therein. The slide member is provided with an oxide coating film on a surface of a base material. The oxide coating film is configured such that (1) when the base material comprises an iron based material, the oxide coating film has a three-layer structure including a first layer comprising Fe 2 O 3 , a second layer comprising Fe 3 O 4 , and a third layer comprising FeO in this order from an outermost surface, (2) the oxide coating film has a dense structure having minute concave/convex portions with a height difference which falls within a range of 0.01µm to 0.1 µm, or (3) when the base material comprises the iron based material, the oxide coating film has a three-layer structure in which the three layers comprise the iron oxides and are different in hardness.
