Zusammenfassung:	To provide a sliding member that reduces falling of a hard phase and has high wear resistance even in high-temperature environment.SOLUTION: A sliding member 10 of this embodiment is made of a stainless-based steel alloy. The sliding member 10 comprises a matrix phase 11, a hard phase 12 and an intermediate hard phase 13. The hard phase 12 has higher hardness than that of the matrix phase 11 and is dispersed in the matrix phase 11. The intermediate hard phase 13 has a hardness between that of the matrix phase 11 and that of the hard phase 12. The hard phase 12 is surrounded by the intermediate hard phase 13.SELECTED DRAWING: Figure 1 【課題】硬質相の脱落を低減し、高温の環境下においても、耐摩耗性が高い摺動部材を提供する。【解決手段】本実施形態の摺動部材１０は、ステンレス系の鋼合金で形成されている。摺動部材１０は、マトリクス相１１、硬質相１２及び中間硬質相１３を備える。硬質相１２は、マトリクス相１１よりも硬度が大きく、マトリクス相１１に分散している。中間硬質相１３は、硬度がマトリクス相１１と硬質相１２との間である。硬質相１２は、中間硬質相１３に包囲されている。【選択図】図１
