Provided is a partially-annular sliding member including a sliding layer including fibrous particles having an average particle size of 5 - 25 µm dispersed in a synthetic resin at a volume ratio of 10 - 35% of the sliding layer. The particles having a major axis length ‰¤ 20 µm are included at a volume ratio of ‰¥ 10% to total particles. A sliding surface side area is defined from the sliding surface and has a thickness of 25% of a sliding layer thickness T, where the fibrous particles having a major axis length of ‰¥ 20 µm have a dispersion index of 1.1 - 6. An interface side area is defined from the interface and has a thickness of 25% of T, where the dispersion index is 1.1 - 6. An intermediate area is defined between the both areas, where the dispersion index is 0.1 to less than 1.
